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/mainnets/umee/monitoring/umee-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 umee 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 umee-mainnet-monitoring
cd umee-mainnet-monitoring
wget https://raw.githubusercontent.com/L0vd/chain-services/main/mainnets/umee/monitoring/monitor.sh
wget https://raw.githubusercontent.com/L0vd/chain-services/main/mainnets/umee/monitoring/telegraf.conf
wget https://raw.githubusercontent.com/L0vd/chain-services/main/mainnets/umee/monitoring/variables.sh

nano variables.sh

Insert your parameters to variables.sh:

• full path to umee binary to COS_BIN_NAME ( check which umeed)

• node PRC port to COS_PORT_RPC ( check in file path_to_umee_node_config/config/config.toml)

• node validator address to COS_VALOPER ( like umeevaloper********)

Save changes in variables.sh and enable execution permissions:

chmod +x monitor.sh variables.sh

Create telegraf service for umee-mainnet-node monitoring

Edit telegraf configuration

sudo mv /etc/telegraf/telegraf.conf /etc/telegraf/telegraf.conf.orig
sudo mv telegraf_umee_mainnet.conf /etc/telegraf/telegraf_umee_mainnet.conf

Restart telegraf service

sudo systemctl daemon-reload
sudo systemctl enable telegraf_umee_mainnet
sudo systemctl restart telegraf_umee_mainnet

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:

Dashboard link

Screenshot_1

Screenshot_2

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 umeed binary

Vali Rank

Your node stake rank

Active validator numbers

Total number of active validators

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