Chain Pulse

Collect packets relayed to and from a given blockchain, computing which packets are effected or not and by whom they were relayed.

The collected data is stored in a SQLite database and the metrics are exported to Prometheus.

Installation

  1. Clone this repository

    $ git clone https://github.com/informalsystems/chainpulse
    
  2. Build the chainpulse executable

    $ cargo build --release
    
  3. The chainpulse executable can now be found in target/release

Configuration

Create a configuration file at chainpulse.toml with the following content:

[chains]
endpoints = [
  { name = "neutron", comet_version = "0.34", url = "wss://neutron-rpc.lavenderfive.com/websocket" },
  { name = "osmosis", comet_version = "0.34", url = "wss://rpc.osmosis.zone/websocket" },
]

[database]
path = "data.db"

[metrics]
enabled = true
port    = 3000

Note: The comet_version field is optional and defaults to "0.34".

Usage

Collect and analyze txs containing IBC messages, export the collected metrics for Prometheus

Usage: chainpulse [OPTIONS]

Options:
  -c, --config <CONFIG>  Path to the configuration file [default: chainpulse.toml]
  -h, --help             Print help

Run the collector using the configuration file above to collect packet metrics on Osmosis and Neutron:

$ chainpulse --config chainpulse.toml

Prometheus Metrics

The built-in HTTP server at /metrics exports the following Prometheus metrics:

# HELP ibc_effected_packets The number of IBC packets that are effected
# TYPE ibc_effected_packets counter
ibc_effected_packets{chain_id, src_channel, src_port, dst_channel, dst_port, signer, memo}
# HELP ibc_uneffected_packets The number of IBC packets that are not effected
# TYPE ibc_uneffected_packets counter
ibc_uneffected_packets{chain_id, src_channel, src_port, dst_channel, dst_port, signer, memo}
# HELP ibc_frontrun_counter The number of times a signer gets frontrun by the original signer
# TYPE ibc_frontrun_counter counter
ibc_frontrun_counter{chain_id, src_channel, src_port, dst_channel, dst_port, signer, frontrunned_by, memo, effected_memo}

# HELP ibc_stuck_packets The number of packets stuck on an IBC channel
# TYPE ibc_stuck_packets gauge
ibc_stuck_packets{dst_chain,src_chain,src_channel} 1

Internal metrics

The following internal metrics are also available, for monitor Chain Pulse itself:

# HELP chainpulse_chains The number of chains being monitored
# TYPE chainpulse_chains gauge
chainpulse_chains 2
# HELP chainpulse_packets The number of packets processed
# TYPE chainpulse_packets counter
chainpulse_packets{chain_id}
# HELP chainpulse_reconnects The number of times we had to reconnect to the WebSocket
# TYPE chainpulse_reconnects counter
chainpulse_reconnects{chain_id}
# HELP chainpulse_txs The number of txs processed
# TYPE chainpulse_txs counter
chainpulse_txs{chain_id}
