Collectors

Community contributed and maintained collectors live in here.

Installation

If you would like to install a collector from the netdata/community repo please follow the instructions below.

In general the below steps should be sufficient to use a third party collector.

  1. Download collector code file into folder expected by Netdata.
  2. Download default collector configuration file into folder expected by Netdata.
  3. Edit configuration file from step 2 if required.
  4. Enable collector.
  5. Restart Netdata

For example below are the steps to enable the Python ClickHouse collector.

# download python collector script to /usr/libexec/netdata/python.d/
$ sudo wget https://raw.githubusercontent.com/netdata/community/main/collectors/python.d.plugin/clickhouse/clickhouse.chart.py -O /usr/libexec/netdata/python.d/clickhouse.chart.py

# (optional) download default .conf to /etc/netdata/python.d/
$ sudo wget https://raw.githubusercontent.com/netdata/community/main/collectors/python.d.plugin/clickhouse/clickhouse.conf -O /etc/netdata/python.d/clickhouse.conf

# enable collector by adding line a new line with "clickhouse: yes" to /etc/netdata/python.d.conf file
# this will append to the file if it already exists or create it if not
$ sudo echo "clickhouse: yes" >> /etc/netdata/python.d.conf

# (optional) edit clickhouse.conf if needed
$ sudo vi /etc/netdata/python.d/clickhouse.conf

# restart netdata 
# see docs for more information: https://learn.netdata.cloud/docs/configure/start-stop-restart
$ sudo systemctl restart netdata

Alternatively you can use this helper script to automate the above steps.

# download and install the clickhouse collector
sudo wget -O /tmp/install-collector.sh https://raw.githubusercontent.com/netdata/community/main/utilities/install-collector.sh && sudo bash /tmp/install-collector.sh python.d.plugin/clickhouse

Other collectors

These community plugins are maintained in separate repositories and come with their own installation instructions.

  • netdata-needrestart - Check/graph the number of processes/services/kernels that should be restarted after upgrading packages.
  • netdata-debsecan - Check/graph the number of CVEs in currently installed packages.
  • netdata-logcount - Check/graph the number of syslog messages, by level over time.
  • netdata-apt - Check/graph and alert on the number of upgradeable packages, and available distribution upgrades.
