# Monitoring

## Monitoring

Advantages of using our free service:

* Our monitoring service is working on dedicated server (24/7 online)
* No need to install database (InfluxDB)
* No need to install and configure Grafana Dashboard
* On Grafana dashboard you will find all necessary metrics of your node (we use this monitoring service by ourselves, so we've configured dashboard properly)

## One line installation:

```
. <(wget -qO- https://raw.githubusercontent.com/L0vd/chain-services/main/testnets/andromeda/monitoring/andromeda-monitoring-install.sh)
```

## OR Manual installation of telegraf and monitoring script

Install telegraf

```
sudo apt update
sudo apt -y install curl jq bc

# install telegraf
wget https://dl.influxdata.com/telegraf/releases/telegraf_1.14.1-1_amd64.deb
dpkg -i telegraf_*.deb

sudo systemctl enable --now telegraf
sudo systemctl is-enabled telegraf

# make the telegraf user sudo and adm to be able to execute scripts as andromeda user
sudo adduser telegraf sudo
sudo adduser telegraf adm
sudo -- bash -c 'echo "telegraf ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers'
```

You can check telegraf service status:

```
sudo systemctl status telegraf
```

Status can be not ok with default Telegraf's config. Next steps will fix it.

Get files from this project repo and copy variable script template

```
cd $HOME
mkdir andromeda-monitoring
cd andromeda-monitoring
wget https://raw.githubusercontent.com/L0vd/chain-services/main/testnets/andromeda/monitoring/monitor.sh
wget https://raw.githubusercontent.com/L0vd/chain-services/main/testnets/andromeda/monitoring/telegraf.conf
wget https://raw.githubusercontent.com/L0vd/chain-services/main/testnets/andromeda/monitoring/variables.sh
```

```
nano variables.sh
```

Insert your parameters to **variables.sh**:

* full path to andromeda binary to COS\_BIN\_NAME ( check `which andromedad`)
* node PRC port to COS\_PORT\_RPC ( check in file `path_to_andromeda_node_config/config/config.toml`)
* node validator address to COS\_VALOPER ( like `andrvaloper********`)

Save changes in variables.sh and enable execution permissions:

```
chmod +x monitor.sh variables.sh
```

Create telegraf service for andromeda-node monitoring

```

Edit telegraf configuration

```
sudo mv /etc/telegraf/telegraf.conf /etc/telegraf/telegraf.conf.orig
sudo mv telegraf.conf /etc/telegraf/telegraf_andromeda.conf
```

Restart telegraf service

```
sudo systemctl daemon-reload
sudo systemctl enable telegraf_andromeda
sudo systemctl restart telegraf_andromeda
```

### Dashboard interface

Dashboard has main cosmos-based node information and common system metrics. There is a description for each metric.

Go to our comunity dashboard and select you node from the server list:

#### Mon health

Complex parameter can show problem concerning receiving metrics from node. Normal value is "OK"

#### Sync status

Node catching\_up parameter

#### Block height

Latest blockheight of node

#### Time since latest block

Time interval in seconds between taking the metric and node latest block time. Value greater 15s may indicate some kind of synchronization problem.

#### Peers

Number of connected peers

#### Jailed status

Validator jailed status.

#### Missed blocks

Number of missed blocks in 10000 blocks running window. If the validator misses more than 500 blocks, it will end up in jail.

#### Bonded status

Validator stake bonded info

#### Voting power

Validator voting power. If the value of this parameter is zero, your node isn't in the active pool of validators

#### Delegated tokens

Number of delegated tokens

#### Version

Version of andromedad binary

#### Vali Rank

Your node stake rank

#### Active validator numbers

Total number of active validators

#### Other common system metrics: CPU/RAM/FS load, etc.
