+Example scripts for User-space, Statically Defined Tracing (USDT)
+=================================================================
+
+This directory contains scripts showcasing User-space, Statically Defined
+Tracing (USDT) support for Dash Core on Linux using. For more information on
+USDT support in Dash Core see the [USDT documentation].
+
+[USDT documentation]: ../../doc/tracing.md
+
+
+Examples for the two main eBPF front-ends, [bpftrace] and
+[BPF Compiler Collection (BCC)], with support for USDT, are listed. BCC is used
+for complex tools and daemons and `bpftrace` is preferred for one-liners and
+shorter scripts.
+
+[bpftrace]: https://github.com/iovisor/bpftrace
+[BPF Compiler Collection (BCC)]: https://github.com/iovisor/bcc
+
+
+To develop and run bpftrace and BCC scripts you need to install the
+corresponding packages. See [installing bpftrace] and [installing BCC] for more
+information. For development there exist a [bpftrace Reference Guide], a
+[BCC Reference Guide], and a [bcc Python Developer Tutorial].
+
+[installing bpftrace]: https://github.com/iovisor/bpftrace/blob/master/INSTALL.md
+[installing BCC]: https://github.com/iovisor/bcc/blob/master/INSTALL.md
+[bpftrace Reference Guide]: https://github.com/iovisor/bpftrace/blob/master/docs/reference_guide.md
+[BCC Reference Guide]: https://github.com/iovisor/bcc/blob/master/docs/reference_guide.md
+[bcc Python Developer Tutorial]: https://github.com/iovisor/bcc/blob/master/docs/tutorial_bcc_python_developer.md
+
+## Examples
+
+The bpftrace examples contain a relative path to the `dashd` binary. By
+default, the scripts should be run from the repository-root and assume a
+self-compiled `dashd` binary. The paths in the examples can be changed, for
+example, to point to release builds if needed. See the
+[Dash Core USDT documentation] on how to list available tracepoints in your
+`dashd` binary.
+
+[Dash Core USDT documentation]: ../../doc/tracing.md#listing-available-tracepoints
+
+**WARNING: eBPF programs require root privileges to be loaded into a Linux
+kernel VM. This means the bpftrace and BCC examples must be executed with root
+privileges. Make sure to carefully review any scripts that you run with root
+privileges first!**
+
+### log_p2p_traffic.bt
+
+A bpftrace script logging information about inbound and outbound P2P network
+messages. Based on the `net:inbound_message` and `net:outbound_message`
+tracepoints.
+
+By default, `bpftrace` limits strings to 64 bytes due to the limited stack size
+in the eBPF VM. For example, Tor v3 addresses exceed the string size limit which
+results in the port being cut off during logging. The string size limit can be
+increased with the `BPFTRACE_STRLEN` environment variable (`BPFTRACE_STRLEN=70`
+works fine).
+
+```
+$ bpftrace contrib/tracing/log_p2p_traffic.bt
+```
+
+Output

+### log_raw_p2p_msgs.py
+
+A BCC Python script showcasing eBPF and USDT limitations when passing data
+larger than about 32kb. Based on the `net:inbound_message` and
+`net:outbound_message` tracepoints.
+
+Dash P2P messages can be larger than 32kb (e.g. `tx`, `block`, ...). The
+eBPF VM's stack is limited to 512 bytes, and we can't allocate more than about
+32kb for a P2P message in the eBPF VM. The **message data is cut off** when the
+message is larger than MAX_MSG_DATA_LENGTH (see script). This can be detected
+in user-space by comparing the data length to the message length variable. The
+message is cut off when the data length is smaller than the message length.
+A warning is included with the printed message data.
+
+Data is submitted to user-space (i.e. to this script) via a ring buffer. The
+throughput of the ring buffer is limited. Each p2p_message is about 32kb in
+size. In- or outbound messages submitted to the ring buffer in rapid
+succession fill the ring buffer faster than it can be read. Some messages are
+lost. BCC prints: `Possibly lost 2 samples` on lost messages.
+
+
+```
+$ python3 contrib/tracing/log_raw_p2p_msgs.py ./src/dashd
+```

+### connectblock_benchmark.bt
+
+A `bpftrace` script to benchmark the `ConnectBlock()` function during, for
+example, a blockchain re-index. Based on the `validation:block_connected` USDT
+tracepoint.
+
+The script takes three positional arguments. The first two arguments, the start,
+and end height indicate between which blocks the benchmark should be run. The
+third acts as a duration threshold in milliseconds. When the `ConnectBlock()`
+function takes longer than the threshold, information about the block, is
+printed. For more details, see the header comment in the script.
+
+The following command can be used to benchmark, for example, `ConnectBlock()`
+between height 20000 and 38000 on SigNet while logging all blocks that take
+longer than 25ms to connect.
+
+```
+$ bpftrace contrib/tracing/connectblock_benchmark.bt 20000 38000 25
+```
+
+In a different terminal, starting Dash Core in SigNet mode and with
+re-indexing enabled.
+
+```
+$ ./src/dashd -signet -reindex
+```
+
+This produces the following output.
+```

+### log_utxos.bt
+
+A `bpftrace` script to log information about the coins that are added, spent, or
+uncached from the UTXO set. Based on the `utxocache:add`, `utxocache:spend` and
+`utxocache:uncache` tracepoints.
+
+```bash
+$ bpftrace contrib/tracing/log_utxos.bt
+```
+
+This should produce an output similar to the following. If you see bpftrace
+warnings like `Lost 24 events`, the eBPF perf ring-buffer is filled faster
+than it is being read. You can increase the ring-buffer size by setting the
+ENV variable `BPFTRACE_PERF_RB_PAGES` (default 64) at a cost of higher
+memory usage. See the [bpftrace reference guide] for more information.

+""" Demonstration of eBPF limitations and the effect on USDT with the
+    net:inbound_message and net:outbound_message tracepoints. """
+
+# This script shows a limitation of eBPF when data larger than 32kb is passed to
+# user-space. It uses BCC (https://github.com/iovisor/bcc) to load a sandboxed
+# eBPF program into the Linux kernel (root privileges are required). The eBPF
+# program attaches to two statically defined tracepoints. The tracepoint
+# 'net:inbound_message' is called when a new P2P message is received, and
+# 'net:outbound_message' is called on outbound P2P messages. The eBPF program
+# submits the P2P messages to this script via a BPF ring buffer. The submitted
+# messages are printed.
+
+# eBPF Limitations:
+#
+# Dash P2P messages can be larger than 32kb (e.g. tx, block, ...). The eBPF
+# VM's stack is limited to 512 bytes, and we can't allocate more than about 32kb
+# for a P2P message in the eBPF VM. The message data is cut off when the message
+# is larger than MAX_MSG_DATA_LENGTH (see definition below). This can be detected
+# in user-space by comparing the data length to the message length variable. The
+# message is cut off when the data length is smaller than the message length.
+# A warning is included with the printed message data.
+#
+# Data is submitted to user-space (i.e. to this script) via a ring buffer. The
+# throughput of the ring buffer is limited. Each p2p_message is about 32kb in
+# size. In- or outbound messages submitted to the ring buffer in rapid
+# succession fill the ring buffer faster than it can be read. Some messages are
+# lost.
+#
+# BCC prints: "Possibly lost 2 samples" on lost messages.

+# User-space, Statically Defined Tracing (USDT) for Dash Core
+
+Dash Core includes statically defined tracepoints to allow for more
+observability during development, debugging, code review, and production usage.
+These tracepoints make it possible to keep track of custom statistics and
+enable detailed monitoring of otherwise hidden internals. They have
+little to no performance impact when unused.

+1. The tracing script compiles the eBPF code and loads the eBPF program into a kernel VM
+2. The eBPF program hooks into one or more tracepoints
+3. When the tracepoint is called, the arguments are passed to the eBPF program
+4. The eBPF program processes the arguments and returns data to the tracing script
+```
+
+The Linux kernel can hook into the tracepoints during runtime and pass data to
+sandboxed [eBPF] programs running in the kernel. These eBPF programs can, for
+example, collect statistics or pass data back to user-space scripts for further
+processing.
+
+[eBPF]: https://ebpf.io/
+
+The two main eBPF front-ends with support for USDT are [bpftrace] and
+[BPF Compiler Collection (BCC)]. BCC is used for complex tools and daemons and
+`bpftrace` is preferred for one-liners and shorter scripts. Examples for both can
+be found in [contrib/tracing].

+## Tracepoint documentation
+
+The currently available tracepoints are listed here.
+
+### Context `net`
+
+#### Tracepoint `net:inbound_message`
+
+Is called when a message is received from a peer over the P2P network. Passes
+information about our peer, the connection and the message as arguments.
+
+Arguments passed:
+1. Peer ID as `int64`
+2. Peer Address and Port (IPv4, IPv6, Tor v3, I2P, ...) as `pointer to C-style String` (max. length 68 characters)
+3. Connection Type (inbound, feeler, outbound-full-relay, ...) as `pointer to C-style String` (max. length 20 characters)
+4. Message Type (inv, ping, getdata, addrv2, ...) as `pointer to C-style String` (max. length 20 characters)
+5. Message Size in bytes as `uint64`
+6. Message Bytes as `pointer to unsigned chars` (i.e. bytes)
+
+Note: The message is passed to the tracepoint in full, however, due to space
+limitations in the eBPF kernel VM it might not be possible to pass the message
+to user-space in full. Messages longer than a 32kb might be cut off. This can
+be detected in tracing scripts by comparing the message size to the length of
+the passed message.
+
+#### Tracepoint `net:outbound_message`
+
+Is called when a message is send to a peer over the P2P network. Passes
+information about our peer, the connection and the message as arguments.
+
+Arguments passed:
+1. Peer ID as `int64`
+2. Peer Address and Port (IPv4, IPv6, Tor v3, I2P, ...) as `pointer to C-style String` (max. length 68 characters)
+3. Connection Type (inbound, feeler, outbound-full-relay, ...) as `pointer to C-style String` (max. length 20 characters)
+4. Message Type (inv, ping, getdata, addrv2, ...) as `pointer to C-style String` (max. length 20 characters)
+5. Message Size in bytes as `uint64`
+6. Message Bytes as `pointer to unsigned chars` (i.e. bytes)
+
+Note: The message is passed to the tracepoint in full, however, due to space
+limitations in the eBPF kernel VM it might not be possible to pass the message
+to user-space in full. Messages longer than a 32kb might be cut off. This can
+be detected in tracing scripts by comparing the message size to the length of
+the passed message.
+
+### Context `validation`
+
+#### Tracepoint `validation:block_connected`
+
+Is called *after* a block is connected to the chain. Can, for example, be used
+to benchmark block connections together with `-reindex`.
+
+Arguments passed:
+1. Block Header Hash as `pointer to unsigned chars` (i.e. 32 bytes in little-endian)
+2. Block Height as `int32`
+3. Transactions in the Block as `uint64`
+4. Inputs spend in the Block as `int32`
+5. SigOps in the Block (excluding coinbase SigOps) `uint64`
+6. Time it took to connect the Block in microseconds (µs) as `uint64`
+
+### Context `utxocache`
+
+The following tracepoints cover the in-memory UTXO cache. UTXOs are, for example,
+added to and removed (spent) from the cache when we connect a new block.
+**Note**: Dash Core uses temporary clones of the _main_ UTXO cache
+(`chainstate.CoinsTip()`). For example, the RPCs `generateblock` and
+`getblocktemplate` call `TestBlockValidity()`, which applies the UTXO set
+changes to a temporary cache. Similarly, mempool consistency checks, which are
+frequent on regtest, also apply the the UTXO set changes to a temporary cache.
+Changes to the _main_ UTXO cache and to temporary caches trigger the tracepoints.
+We can't tell if a temporary cache or the _main_ cache was changed.
+
+#### Tracepoint `utxocache:flush`
+
+Is called *after* the in-memory UTXO cache is flushed.
+
+Arguments passed:
+1. Time it took to flush the cache microseconds as `int64`
+2. Flush state mode as `uint32`. It's an enumerator class with values `0`
+   (`NONE`), `1` (`IF_NEEDED`), `2` (`PERIODIC`), `3` (`ALWAYS`)
+3. Cache size (number of coins) before the flush as `uint64`
+4. Cache memory usage in bytes as `uint64`
+5. If pruning caused the flush as `bool`
+
+#### Tracepoint `utxocache:add`
+
+Is called when a coin is added to a UTXO cache. This can be a temporary UTXO cache too.
+
+Arguments passed:
+1. Transaction ID (hash) as `pointer to unsigned chars` (i.e. 32 bytes in little-endian)
+2. Output index as `uint32`
+3. Block height the coin was added to the UTXO-set as  `uint32`
+4. Value of the coin as `int64`
+5. If the coin is a coinbase as `bool`
+
+#### Tracepoint `utxocache:spent`
+
+Is called when a coin is spent from a UTXO cache. This can be a temporary UTXO cache too.
+
+Arguments passed:
+1. Transaction ID (hash) as `pointer to unsigned chars` (i.e. 32 bytes in little-endian)
+2. Output index as `uint32`
+3. Block height the coin was spent, as `uint32`
+4. Value of the coin as `int64`
+5. If the coin is a coinbase as `bool`
+
+#### Tracepoint `utxocache:uncache`
+
+Is called when a coin is purposefully unloaded from a UTXO cache. This
+happens, for example, when we load an UTXO into a cache when trying to accept
+a transaction that turns out to be invalid. The loaded UTXO is uncached to avoid
+filling our UTXO cache up with irrelevant UTXOs.
+
+Arguments passed:
+1. Transaction ID (hash) as `pointer to unsigned chars` (i.e. 32 bytes in little-endian)
+2. Output index as `uint32`
+3. Block height the coin was uncached, as `uint32`
+4. Value of the coin as `int64`
+5. If the coin is a coinbase as `bool`
+
+## Adding tracepoints to Dash Core
+
+To add a new tracepoint, `#include <util/trace.h>` in the compilation unit where
+the tracepoint is inserted. Use one of the `TRACEx` macros listed below
+depending on the number of arguments passed to the tracepoint. Up to 12
+arguments can be provided. The `context` and `event` specify the names by which
+the tracepoint is referred to. Please use `snake_case` and try to make sure that
+the tracepoint names make sense even without detailed knowledge of the
+implementation details. Do not forget to update the tracepoint list in this
+document.
+
+```c
+#define TRACE(context, event)
+#define TRACE1(context, event, a)
+#define TRACE2(context, event, a, b)
+#define TRACE3(context, event, a, b, c)
+#define TRACE4(context, event, a, b, c, d)
+#define TRACE5(context, event, a, b, c, d, e)
+#define TRACE6(context, event, a, b, c, d, e, f)
+#define TRACE7(context, event, a, b, c, d, e, f, g)
+#define TRACE8(context, event, a, b, c, d, e, f, g, h)
+#define TRACE9(context, event, a, b, c, d, e, f, g, h, i)
+#define TRACE10(context, event, a, b, c, d, e, f, g, h, i, j)
+#define TRACE11(context, event, a, b, c, d, e, f, g, h, i, j, k)
+#define TRACE12(context, event, a, b, c, d, e, f, g, h, i, j, k, l)
+```
+
+For example:
+
+```C++
+TRACE6(net, inbound_message,
+    pnode->GetId(),
+    pnode->m_addr_name.c_str(),
+    pnode->ConnectionTypeAsString().c_str(),
+    sanitizedType.c_str(),
+    msg.data.size(),
+    msg.data.data()
+);
+```
+
+### Guidelines and best practices
+
+#### Clear motivation and use-case
+Tracepoints need a clear motivation and use-case. The motivation should
+outweigh the impact on, for example, code readability. There is no point in
+adding tracepoints that don't end up being used.
+
+#### Provide an example
+When adding a new tracepoint, provide an example. Examples can show the use case
+and help reviewers testing that the tracepoint works as intended. The examples
+can be kept simple but should give others a starting point when working with
+the tracepoint. See existing examples in [contrib/tracing/].
+
+[contrib/tracing/]: ../contrib/tracing/
+
+#### No expensive computations for tracepoints
+Data passed to the tracepoint should be inexpensive to compute. Although the
+tracepoint itself only has overhead when enabled, the code to compute arguments
+is always run - even if the tracepoint is not used. For example, avoid
+serialization and parsing.
+
+#### Semi-stable API
+Tracepoints should have a semi-stable API. Users should be able to rely on the
+tracepoints for scripting. This means tracepoints need to be documented, and the
+argument order ideally should not change. If there is an important reason to
+change argument order, make sure to document the change and update the examples
+using the tracepoint.
+
+#### eBPF Virtual Machine limits
+Keep the eBPF Virtual Machine limits in mind. eBPF programs receiving data from
+the tracepoints run in a sandboxed Linux kernel VM. This VM has a limited stack
+size of 512 bytes. Check if it makes sense to pass larger amounts of data, for
+example, with a tracing script that can handle the passed data.
+
+#### `bpftrace` argument limit
+While tracepoints can have up to 12 arguments, bpftrace scripts currently only
+support reading from the first six arguments (`arg0` till `arg5`) on `x86_64`.
+bpftrace currently lacks real support for handling and printing binary data,
+like block header hashes and txids. When a tracepoint passes more than six
+arguments, then string and integer arguments should preferably be placed in the
+first six argument fields. Binary data can be placed in later arguments. The BCC
+supports reading from all 12 arguments.
+
+#### Strings as C-style String
+Generally, strings should be passed into the `TRACEx` macros as pointers to
+C-style strings (a null-terminated sequence of characters). For C++
+`std::strings`, [`c_str()`]  can be used. It's recommended to document the
+maximum expected string size if known.
+
+
+[`c_str()`]: https://www.cplusplus.com/reference/string/string/c_str/
+
+
+## Listing available tracepoints
+
+Multiple tools can list the available tracepoints in a `dashd` binary with
+USDT support.
+
+### GDB - GNU Project Debugger
+
+To list probes in Dash Core, use `info probes` in `gdb`:
+
+```
+$ gdb ./src/dashd
+…
+(gdb) info probes
+Type Provider   Name             Where              Semaphore Object
+stap net        inbound_message  0x000000000014419e /src/dashd
+stap net        outbound_message 0x0000000000107c05 /src/dashd
+stap validation block_connected  0x00000000002fb10c /src/dashd
+…
+```
+
+### With `readelf`
+
+The `readelf` tool can be used to display the USDT tracepoints in Dash Core.
+Look for the notes with the description `NT_STAPSDT`.
+
+```
+$ readelf -n ./src/dashd | grep NT_STAPSDT -A 4 -B 2
+Displaying notes found in: .note.stapsdt
+  Owner                 Data size	Description
+  stapsdt              0x0000005d	NT_STAPSDT (SystemTap probe descriptors)
+    Provider: net
+    Name: outbound_message
+    Location: 0x0000000000107c05, Base: 0x0000000000579c90, Semaphore: 0x0000000000000000
+    Arguments: -8@%r12 8@%rbx 8@%rdi 8@192(%rsp) 8@%rax 8@%rdx
+…
+```
+
+### With `tplist`
+
+The `tplist` tool is provided by BCC (see [Installing BCC]). It displays kernel
+tracepoints or USDT probes and their formats (for more information, see the
+[`tplist` usage demonstration]). There are slight binary naming differences
+between distributions. For example, on
+[Ubuntu the binary is called `tplist-bpfcc`][ubuntu binary].
+
+[Installing BCC]: https://github.com/iovisor/bcc/blob/master/INSTALL.md
+[`tplist` usage demonstration]: https://github.com/iovisor/bcc/blob/master/tools/tplist_example.txt
+[ubuntu binary]: https://github.com/iovisor/bcc/blob/master/INSTALL.md#ubuntu---binary
