Cosmos - Prometheus metrics collection toolset

### Description

The repository is the set of tools to collect cosmos node networking performance.

The metrics collection repository contains three key directories: prometheus, gaia, and metrics.



The metrics are being collected each 5s triggered by Prometheus that queries middle layer app written in go and running on `http://127.0.0.1:3000` and underneath operates with a cosmos node running on `http://127.0.0.1:26657`.



```Gaia Node(API) <- Go App <- Prometheus```



The application uses only two endpoints: `http://localhost:26657/status`, `http://localhost:26657/net_info` with three properties collected: `n_peers, latest_block_time, latest_block_height` which can be easilly tuned. 



Full specifications of Cosmos API can be found by the link https://docs.tendermint.com/v0.34/rpc/#/.



### Cosmos Installation Manual

Installation of the cosmos network even on a testnet might be tricky, gaia has undergone multiple updates with a variety of testnets running. The documentation might also be not always correct having wrong or pointing to outdated properties, or readme files.



I encourage you to read the official documentation https://hub.cosmos.network/main/hub-tutorials/join-testnet.html which will require values for properties `trust_height`, `trust_hash`, `rpc_servers`, `seeds` to be assigned, which you may find this repo.



Testnet explorer: https://explorer.theta-testnet.polypore.xyz/ 


Testent id: theta-testnet-001



The installation itself.



#### 1. Install and build node with network genesis file downloaded

```

git clone https://github.com/cosmos/testnets/tree/master/public

git checkout v7.0.0



make install

gaiad init CUSTOM_MONIKER --chain-id theta-testnet-001



wget https://github.com/cosmos/testnets/raw/master/public/genesis.json.gz

gunzip genesis.json.gz

cp genesis.json $HOME/.gaia/config/genesis.json



gaiad config chain-id theta-testnet-001

```



#### 2. Edit network settings

See https://hub.cosmos.network/main/hub-tutorials/join-testnet.html 


Or just copy the config files from this repo to Gaia home dir `$HOME/.gaia/config`. 

```

cp gaia/app.toml $HOME/.gaia/config

cp gaia/client.toml $HOME/.gaia/config

cp gaia/config.toml $HOME/.gaia/config

```



#### 3. Launch gaia network

```

gaiad start --x-crisis-skip-assert-invariants

```



### Metrics Go Installation

Clone this repository, if was not already clonned - `git clone https://github.com/ivanproskuryakov/gaia-metrics` 


If required, install golang - https://go.dev/doc/install 



```

cd mertics/go

go build app.go

./app

```

![metrics running](img/metrics_go.png)



### Metrics Go Daemon

```

nano /etc/systemd/system/gaiametrics.service



sudo systemctl daemon-reload

sudo systemctl start gaiametrics.service

sudo systemctl enable gaiametrics.service

```



See metrics running:

```

journalctl -fu gaiametrics.service

journalctl -u gaiametrics.service -f

```



### Prometheus Installation

Installation of prometheus is pretty straightforward, see  https://prometheus.io/download/.

Prometheus operates based on configs, which need to be tuned or replaced with the config from this repo, see `prometheus/prometeus.yml`



### Prometheus Daemon

```

nano /etc/systemd/system/prometheus.service



sudo systemctl daemon-reload

sudo systemctl start prometheus.service

sudo systemctl enable prometheus.service

```

### Metrics Node Application

The repository contains metrics application wrriten with node.js and TypeScript, see `metrics/node` directory

```

npm run dev

npm run build

http://127.0.0.1:3000/

```



### Cosmos Installation Ansible

Installation of cosmos with ansible.
