# Install
## Using Go
If you already have [Go] installed, you can use to Go toolchain to build from
source and install it for you (under `$GOPATH/bin`):
```console
$ GO111MODULE=on go get github.com/cirocosta/monero-exporter/cmd/monero-exporter
go: downloading github.com/cirocosta/monero-exporter v0.0.3
$ monero-exporter --help
Prometheus exporter for monero metrics
Usage:
monero-exporter [flags]
...
```
Note that this will install the latest tagged release (not necessarily the
latest code).
## From releases
In the [releases page] you'll find the pre-compiled releases for each platform.
### "yeah yeah, I trust the interwebs" mode
```bash
export VERSION=0.0.3
curl -SL -o- https://github.com/cirocosta/monero-exporter/releases/download/v$VERSION/monero-exporter_$VERSION_Linux_x86_64.tar.gz | \
tar xvzf monero
mv ./monero-exporter /usr/local/bin
```
### "trust, but verify" mode
1. fetch my public key and make sure it matches the expected fingerprint
```console
$ curl -SOL https://utxo.com.br/pgp/public-key.txt
```
now, using `gpg`, derive the fingerprint. it should match the one advertised by
me: `9CD1 1313 8578 59CC 0FAD E93B 6B93 177A 62D0 1DB8` (should be the same as
you can find under my personal account on Twitter: http://twitter.com/cirowrc).
```console
$ gpg --keyid-format long --with-fingerprint ./public-key.txt
pub rsa3072/6B93177A62D01DB8 2021-07-19 [SC] [expires: 2023-07-19]
Key fingerprint = 9CD1 1313 8578 59CC 0FAD E93B 6B93 177A 62D0 1DB8
```
then, import into the key to the keyring so it can be used to validate that I
indeed signed the content advertised.
```console
$ gpg --import ./public-key.txt
gpg: key 6B93177A62D01DB8: public key "..." imported
gpg: Total number processed: 1
gpg: imported: 1
```
2. download the archive for your platform as well as the checksums
```console
$ curl -SOL https://github.com/cirocosta/monero-exporter/releases/download/v0.0.3/monero-exporter_0.0.3_Linux_x86_64.tar.gz
$ curl -SOL https://github.com/cirocosta/monero-exporter/releases/download/v0.0.3/checksums.txt.asc
```
3. verify that you can trust the checksums (that it has been generated and
not tampered with), and then verify that the assets you downloaded are what
they supposed to be
```console
$ gpg --verify ./checksums.txt.asc
gpg: Signature made Mon 19 Jul 2021 02:10:42 PM EDT
gpg: using RSA key 9CD11313857859CC0FADE93B6B93177A62D01DB8
gpg: Good signature from "Ciro ...
```
4. verify that the tarball is what it should be
compute the digest of the tarball
```console
$ sha256sum ./monero-exporter_0.0.3_Linux_x86_64.tar.gz
e2b2214c9371fe3c0333cca7feff3554c56d8d0f377180e39ff50d332639c22d ./monero-exporter_0.0.3_Linux_x86_64.tar.gz
see that it matches what you found in the signed checksums file
$ cat ./checksums.txt.asc | grep e2b2214c9371fe3c0333cca7feff3554c56d8d0f377180e39ff50d332639c22d
e2b2214c9371fe3c0333cca7feff3554c56d8d0f377180e39ff50d332639c22d monero-exporter_0.0.3_Linux_x86_64.tar.gz
```
5. install
```console
$ tar xvzf ./monero-exporter_0.0.3_Linux_x86_64.tar.gz monero
$ mv monero /usr/local/bin
$ monero-exporter version
0.0.3 ...

## About
`monero-exporter` is a single multiplatform binary that extracts metrics out of
a running [monero] node, allowing one to better observe the state of its own
daemon and the network as seen by it.

Use "monero-exporter [command] --help" for more information about a command.
```
It works by issuing remote procedure calls (RPC) to a monero node and based on
the responses it gets, exposing metrics to a Prometheus server querying
`monero-exporter`.
```
PROMETHEUS ---- get /metrics -->---.
^ |
| |
| MONERO-EXPORTER --- get /jsonrpc --> MONEROD
| |
| |
'-------------<-- samples ------'
```
Typically, `monero-exporter` is just one piece of the stack though. A complete
setup usually looks like:
- `monerod`, the monero daemon, is running exposing its daemon RPC for those
interested in it (see [monero-project/monero])
- `monero-exporter` targets that `monerod` RPC port
- [prometheus], configured to scrape `monero-exporter`, asks it for metric
samples, then stores those in its internal timeseries database
- [grafana] then queries that timeseries data using the [promql], displaying
that in dashboards, alerting on thresholds, etc
```

## Installation
You can either install it by using [Go], building the latest tagged release
from scratch
```bash
GO111MODULE=on \
go get github.com/cirocosta/monero-exporter/cmd/monero-exporter
```
or fetching the binary for your corresponding distribution from the [releases
page].
See [INSTALL.md] for details and examples.
## Metrics
Below you'll find the description of the metrics exposed by `monero-exporter`
that are retrieved by a prometheus server, stored in its timeseries database,
and made available for querying by something like Grafana.
Keep in mind that Prometheus gather metrics in a pull-based fashion (see ["Why
do you pull rather than push?"]), and as such, metric samples are based on
information seen at the time that prometheus reached out to the exporter.
While the pull-based approach is very useful for looking at long timeframes and
large number of hosts, it's not very suitable for realtime data (for that,
consider other implementations for push-based systems like [InfluxDB]).
### Last block
This set of metrics is extracted from information gathered regarding the last
block seen by the node at the moment that Prometheus scraped samples from
`monero-exporter`.
Think of it as _"at time X, when I looked at the last block, these were the
pieces of information I could gather from it"_, which when looked at over time
(say, 30d), gives you a pretty good picture of what "all" (more like, _most_)
blocks looked like as long as the interval between those scrapes where short
enough (i.e., in between the mean time for a block to be mined - 2min as of
today).

### Transaction pool
These metrics give you a view of how the transaction pool of this particular
node looked like when Prometheus asked the exporter information about it.
Given the pull-based nature of Prometheus, this will be only as granular as the
frequency of scraping configured for it.
| name | description |
| ---- | ----------- |
| monero_transaction_pool_double_spends | transactions doubly spending outputs |
| monero_transaction_pool_failing_transactions | number of transactions that are marked as failing |
| monero_transaction_pool_fees_micronero_per_kb | distribution of the feeperkb utilized for txns in the pool |
| monero_transaction_pool_fees_monero | total amount of fee being spent in the transaction pool |
| monero_transaction_pool_not_relayed | number of transactions that have not been relayed |
| monero_transaction_pool_older_than_10m | number of transactions that are older than 10m |
| monero_transaction_pool_size_bytes | total size of the transaction pool |
| monero_transaction_pool_spent_key_images | total number of key images spent across all transactions in the pool |
| monero_transaction_pool_transactions | number of transactions in the pool at the moment of the scrape |
| monero_transaction_pool_transactions_age | distribution of for how long transactions have been in the pool |
| monero_transaction_pool_transactions_inputs | distribution of inputs in the pool |
| monero_transaction_pool_transactions_outputs | distribution of outputs in the pool |
| monero_transaction_pool_transactions_size_bytes | distribution of the size of the transactions in the transaction pool |
### RPC
RPC metrics provide an overview of the usage of the RPC endpoints.
Note that `monerod` does not distinguish between `monero-exporter` and other
users (like, a wallet), which means that these metrics will include the
constant querying that `monero-exporter` performs to fetch statistics.
| name | description |
| ---- | ----------- |
| monero_rpc_hits_total | number of hits that a particular rpc method had since startup |
| monero_rpc_seconds_total | amount of time spent service the method since startup |
### P2P Connections
Connection metrics aim at providing information about peers that are fully
connected to the node (thus, transmitting and receiving data to/from our node).
| name | description |
| ---- | ----------- |
| monero_p2p_connections | number of connections to/from this node |
| monero_p2p_connections_age | distribution of age of the connections we have |
| monero_p2p_connections_height | distribution the height of the peers connected to/from us |
| monero_p2p_connections_rx_rate_bps | distribution of data receive rate in bytes/s |
| monero_p2p_connections_tx_rate_bps | distribution of data transmit rate in bytes/s |
### Peerlist
The monero daemon internally keeps track of potential peers to connect to
called peerlists, divided in anchor, white, and gray.
| name | description |
| ---- | ----------- |
| monero_peerlist | number of node entries in the peerlist |
| monero_peerlist_lastseen | distribution of when our peers have been seen |
### Net Stats
Aggregated network statistics, not specific to P2P or RPC.
| name | description |
| ---- | ----------- |
| monero_net_rx_bytes | number of bytes received by this node |
| monero_net_tx_bytes | number of bytes received by this node |
### Info
General information about this node.
| name | description |
| ---- | ----------- |
| monero_info_alternative_blocks | number of blocks alternative to the longest |
| monero_info_block_size_limit | maximum hard limit of a block |
| monero_info_block_size_median | current median size for computing dynamic fees |
| monero_info_mainnet | whether the node is connected to mainnet |
| monero_info_offline | whether the node is offline |
