# Solana Exporter ## Overview The Solana Exporter exports basic monitoring data from a Solana node, using the [Solana RPC API](https://solana.com/docs/rpc). ### Example Usage To use the Solana Exporter, simply run the program with the desired [command line configuration](#Command-Line-Arguments), e.g., ```shell solana-exporter \ -nodekey -nodekey \ -balance-address -balance-address \ -comprehensive-slot-tracking \ -monitor-block-sizes ``` ![Solana Exporter Dashboard Sample](assets/solana-dashboard-screenshot.png) ## Installation ### Build 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: ```shell git clone https://github.com/asymmetric-research/solana-exporter.git cd solana-exporter CGO_ENABLED=0 go build ./cmd/solana-exporter ``` ## 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. ## Metrics ### Overview The table below describes all the metrics collected by the `solana-exporter`: | Metric | Description | Labels | |------------------------------------------------|------------------------------------------------------------------------------------------|-------------------------------| | `solana_validator_active_stake` | Active stake per validator. | `votekey`, `nodekey` | | `solana_validator_last_vote` | Last voted-on slot per validator. | `votekey`, `nodekey` | | `solana_validator_root_slot` | Root slot per validator. | `votekey`, `nodekey` | | `solana_validator_delinquent` | Whether a validator is delinquent. | `votekey`, `nodekey` | | `solana_account_balance` | Solana account balances. | `address` | | `solana_node_version` | Node version of solana.* | `version` | | `solana_node_is_healthy` | Whether the node is healthy.* | N/A | | `solana_node_num_slots_behind` | The number of slots that the node is behind the latest cluster confirmed slot.* | N/A | | `solana_node_minimum_ledger_slot` | The lowest slot that the node has information about in its ledger.* | N/A | | `solana_node_first_available_block` | The slot of the lowest confirmed block that has not been purged from the node's ledger.* | N/A | | `solana_node_transactions_total` | Total number of transactions processed without error since genesis.* | N/A | | `solana_node_slot_height` | The current slot number.* | N/A | | `solana_node_epoch_number` | The current epoch number.* | N/A | | `solana_node_epoch_first_slot` | Current epoch's first slot \[inclusive\].* | N/A | | `solana_node_epoch_last_slot` | Current epoch's last slot \[inclusive\].* | N/A | | `solana_validator_leader_slots_total` | Number of slots processed. | `status`, `nodekey` | | `solana_validator_leader_slots_by_epoch_total` | Number of slots processed per validator. | `status`, `nodekey`, `epoch` | | `solana_cluster_slots_by_epoch_total` | Number of slots processed by the cluster. | `status`, `epoch` | | `solana_validator_inflation_rewards` | Inflation reward earned. | `votekey`, `epoch` | | `solana_validator_fee_rewards` | Transaction fee rewards earned. | `nodekey`, `epoch` | | `solana_validator_block_size` | Number of transactions per block. | `nodekey`, `transaction_type` | | `solana_node_block_height` | The current block height of the node.* | N/A | ***NOTE***: An `*` in the description indicates that the metric **is** tracked in `-light-mode`. ### Labels The table below describes the various metric labels: | Label | Description | Options / Example | |--------------------|-------------------------------------|------------------------------------------------------| | `nodekey` | Validator identity account address. | e.g, `Certusm1sa411sMpV9FPqU5dXAYhmmhygvxJ23S6hJ24` | | `votekey` | Validator vote account address. | e.g., `CertusDeBmqN8ZawdkxK5kFGMwBXdudvWHYwtNgNhvLu` | | `address` | Solana account address. | e.g., `Certusm1sa411sMpV9FPqU5dXAYhmmhygvxJ23S6hJ24` | | `version` | Solana node version. | e.g., `v1.18.23` | | `status` | Whether a slot was skipped or valid | `valid`, `skipped` | | `epoch` | Solana epoch number. | e.g., `663` | | `transaction_type` | General transaction type. | `vote`, `non_vote` |
