Collectd Gnocchi Status

|collectd-gnocchi-status|

Overview

This plugin provides valuable insight into your metrics and measures backlog of Gnocchi when installed in an OpenStack environment. It costs an API call to Gnocchi status API every $interval (set in the collectd config file per the plugin). Gnocchi is a component of the OpenStack Telemetry project for Metric-as-a-Service.

Configuration

1. Assuming you have collectd installed already, append the following plugin details to your collectd.conf config file

   ::

   ``` Globals true

   LogTraces true Interactive false Import "collectd gnocchistatus" interval 30 ```

2. Setup your environment variables in the collectd systemd unit file

   ::

   ``` # Populate the following variables with your stackrc/overcloudrc or openstackrc file # Tenant v1&v2 api, project for v3 api Environment=OSTENANTNAME=admin Environment=OSPROJECTNAME=admin

   Environment=OSPASSWORD=xxxxxxxxxxxxxxxxxxxxxxxxx Environment=OSUSERNAME=admin Environment=OSAUTHURL=http://x.x.x.x:5000/v2.0 Environment=OSCLOUDNAME=overcloud Environment=OSNO_CACHE=True # End Environment variables to configure ```

3. Install plugin

   ::

   [root@overcloud-controller-0 ~]# pip install collectd-gnocchi-status

4. Reload Systemd units

   ::

   [root@overcloud-controller-0 ~]# systemctl daemon-reload

5. Restart collectd

   ::

   [root@overcloud-controller-0 ~]# systemctl restart collectd

6. View metrics on Gnocchi in your TSDB

Graphite storage-aggregation.conf Example

Included in the repo is an example Graphite storage-aggregation.conf (sample-storage-aggregation.conf) to ensure that your Gnocchi status metrics are not lost due to your retention sizing (Ex. 10s:7d,60s:90d,1h:180d) < the interval (30s) this plugin is set to collect and publish samples. Simply copy and paste the example, into your /etc/carbon/storage-aggregation.conf file on your Graphite server prior to pushing these metrics and restart carbon-cache to reload this configuration. If the metrics have already been pushed, you must either use whisper-resize (included with Graphite) or remove the corresponding whisper files after restarting carbon-cache to allow carbon to rebuild them with the new parameters in storage-aggregation.conf.
