This guide helps you configure Monitoring to monitor Redis.
Redis is an open source advanced key-value store. It is often referred to as a data structure server since values can contain strings, hashes, lists, sets and sorted sets. For more information, visit redis.io.
Monitoring discovers Redis services running in your Cloud Platform project if you have the following:
- VM instances with redis in their names.
- Firewall rules that open port 6379.
To see the metrics for Redis, go to Monitoring:
Select Dashboards and then select the Redis dashboard from the list.
Configuring Redis monitoring
The Monitoring agent uses the
hiredis client library
to monitor Redis. After installing Redis, install
hiredis by running the
RHEL and CentOS
sudo yum install epel-release sudo yum install hiredis
Ubuntu 18.04 LTS, 16.04 LTS, and Debian 9
sudo apt-get install libhiredis0.13
Other Debian and Ubuntu
sudo apt-get install libhiredis0.10
sudo zypper install libhiredis0_13
To monitor Redis, perform the following actions on your VM instance after installing the monitoring agent:
Install the Redis configuration file, redis.conf, by running the following command:
(cd /etc/stackdriver/collectd.d/ && sudo curl -O https://raw.githubusercontent.com/Stackdriver/stackdriver-agent-service-configs/master/etc/collectd.d/redis.conf)
If you are using a nonstandard host or port for Redis, as root, edit
redis.confby following the instructions at the top of the file.
Restart the monitoring agent by running the following command:
sudo service stackdriver-agent restart

redis plugin, see
The full list of metrics the Redis plugin monitors is at Agent metrics: redis. The actual metrics collected, and the metrics available in the Monitoring menus, can vary.
