# solana_exporter
# Solana Exporter
## Overview

solana_exporter exports basic monitoring data from a Solana node.
The Solana Exporter exports basic monitoring data from a Solana node, using the
[Solana RPC API](https://solana.com/docs/rpc).

### Example Usage

## Metrics

Metrics tracked with confirmation level `recent`:

- **solana_validator_root_slot** - Latest root seen by each validator.
- **solana_validator_last_vote** - Latest vote by each validator (not necessarily on the majority fork!)
- **solana_validator_delinquent** - Whether node considers each validator to be delinquent.
- **solana_validator_activated_stake** - Active stake for each validator.
- **solana_active_validators** - Total number of active/delinquent validators.

Metrics tracked with confirmation level `max`:
To use the Solana Exporter, simply run the program with the desired
[command line configuration](#Command-Line-Arguments), e.g.,

- **solana_leader_slots_total** - Number of leader slots per leader, grouped by skip status.
- **solana_confirmed_epoch_first_slot** - Current epoch's first slot.
- **solana_confirmed_epoch_last_slot** - Current epoch's last slot.
- **solana_confirmed_epoch_number** - Current epoch.
- **solana_confirmed_slot_height** - Last confirmed slot height observed.
- **solana_confirmed_transactions_total** - Total number of transactions processed since genesis.

Metrics with no confirmation level:
```shell
solana-exporter \
-nodekey <VALIDATOR_IDENTITY_1> -nodekey <VALIDATOR_IDENTITY_2> \
-balance-address <ADDRESS_1> -balance-address <ADDRESS_2> \
-comprehensive-slot-tracking \
-monitor-block-sizes
```

- **solana_node_version** - Current solana-validator node version.

## Installation
### Build

`solana_exporter` can be installed by doing the following. It's assumed you already have `go` installed.
Assuming you already have [Go installed](https://go.dev/doc/install), the `solana-exporter` can be installed by
cloning this repository and building the binary:

```sh
git clone https://github.com/asymmetric-research/solana_exporter.git
cd solana_exporter
CGO_ENABLED=0 go build ./cmd/solana_exporter
```shell
git clone https://github.com/asymmetric-research/solana-exporter.git
cd solana-exporter
CGO_ENABLED=0 go build ./cmd/solana-exporter
```

## Command line arguments
## Configuration
### Command Line Arguments

The exporter is configured via the following command line arguments:

| Option | Description | Default |
|--------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------|
| `-balance-address` | Address to monitor SOL balances for, in addition to the identity and vote accounts of the provided nodekeys - can be set multiple times. | N/A |
| `-comprehensive-slot-tracking` | Set this flag to track `solana_leader_slots_by_epoch` for all validators. | `false` |
| `-http-timeout` | HTTP timeout to use, in seconds. | `60` |
| `-light-mode` | Set this flag to enable light-mode. In light mode, only metrics unique to the node being queried are reported (i.e., metrics such as `solana_inflation_rewards` which are visible from any RPC node, are not reported). | `false` |
| `-listen-address` | Prometheus listen address. | `":8080"` |
| `-monitor-block-sizes` | Set this flag to track block sizes (number of transactions) for the configured validators. | `false` |
| `-nodekey` | Solana nodekey (identity account) representing a validator to monitor - can set multiple times. | N/A |
| `-rpc-url` | Solana RPC URL (including protocol and path), e.g., `"http://localhost:8899"` or `"https://api.mainnet-beta.solana.com"` | `"http://localhost:8899"` |
| `-slot-pace` | This is the time (in seconds) between slot-watching metric collections | `1` |

### Notes on Configuration

* `-light-mode` is incompatible with `-nodekey`, `-balance-address`, `-monitor-block-sizes`, and
`-comprehensive-slot-tracking`, as these options control metrics which are not monitored in `-light-mode`.
* ***WARNING***:
* Configuring `-comprehensive-slot-tracking` will lead to potentially thousands of new Prometheus metrics being
created every epoch.
* Configuring `-monitor-block-sizes` with many `-nodekey`'s can potentially strain the node - every block produced
by a configured `-nodekey` is fetched, and a typical block can be as large as 5MB.

You typically only need to set the RPC URL, pointing to one of your own nodes:

./solana_exporter -rpc-url=http://yournode:8899

If you want verbose logs, specify `-v=<num>`. Higher verbosity means more debug output. For most users, the default
verbosity level is fine. If you want detailed log output for missed blocks, run with `-v=1`.

```
Usage of solana_exporter:
-add_dir_header
If true, adds the file directory to the header of the log messages
-alsologtostderr
log to standard error as well as files (no effect when -logtostderr=true)
-balance-address value
Address to monitor SOL balances for, in addition to the identity and vote accounts of the provided nodekeys - can be set multiple times.
-comprehensive-slot-tracking
Set this flag to track solana_leader_slots_by_epoch for ALL validators. Warning: this will lead to potentially thousands of new Prometheus metrics being created every epoch.
-http-timeout int
HTTP timeout to use, in seconds. (default 60)
-listen-address string
Listen address (default ":8080")
-log_backtrace_at value
when logging hits line file:N, emit a stack trace
-log_dir string
If non-empty, write log files in this directory (no effect when -logtostderr=true)
-log_file string
If non-empty, use this log file (no effect when -logtostderr=true)
-log_file_max_size uint
Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
-logtostderr
log to standard error instead of files (default true)
-monitor-block-sizes
Set this flag to track block sizes (number of transactions) for the configured validators. Warning: this might grind the RPC node.
-nodekey value
Solana nodekey (identity account) representing validator to monitor - can set multiple times.
-one_output
If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
-rpc-url string
Solana RPC URL (including protocol and path), e.g., 'http://localhost:8899' or 'https://api.mainnet-beta.solana.com' (default "http://localhost:8899")
-skip_headers
If true, avoid header prefixes in the log messages
-skip_log_headers
If true, avoid headers when opening log files (no effect when -logtostderr=true)
-stderrthreshold value
logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=true) (default 2)
-v value
number for the log level verbosity
-vmodule value
comma-separated list of pattern=N settings for file-filtered logging
```
