HI Guys I am facing issues relaying metrics to Graphite from Sensu server (Core 1.2). I am able to send test data to graphite as follows.
PORT=2003
SERVER=graphite.your.org
echo "local.random.diceroll 4 date +%s" | nc {SERVER} {PORT}

Also I have below relay.json file in my /etc/sensu/conf.d
{
“relay”: {
“graphite”: {
“host”: “”,
“port”: 2003,
“max_queue_size”: 16384
}
}
}

Also in /etc/sensu/extensions i have handlers/relay.rb and mutators/metrics.rb, but i do not see any metrics being relayed to Graphite. Please advise. thank you

  1. What have you already tried? Please include links to gists and/or code blocks (if relatively small)

  2. Tell us about your setup, this should include OS, version of Sensu, version of Sensu components (redis, rabbitmq), plugin versions (if applicable), anything special about your setup such as an airgapped network or strict ACLs
    Sensu Core 1.2, CentOS 7.5, SELinux Permissive , No Firewall rules

  3. Is there a Github issue related to your issue? No

  4. Is there anything else that can help us effectively help you? No

I don’t have experience with WizardVan, but if handler and mutator extensions are being loaded as you expect, you should see loading extension file messages in /var/log/sensu/sensu-server.log.

Can you confirm that you see these extensions being loaded?

Secondly, your description of the issue doesn’t indicate how you have configured check handlers to send their data to the WizardVan relay.

Can you confirm that your check definitions include "metrics": true and specify the relay handler in their list of handlers?

@cwjohnston thanks a lot for the reply. I have configured checks on a windows vm as below. In Uchiwa i can see the correct status of check results.
{
“checks”: {
“cpu_load”: {
“command”: “Powershell.exe -NonInteractive -NoProfile -ExecutionPolicy Bypass -NoLogo -File C:\etc\sensu\plugins\check-windows-cpu-load.ps1 85 95”,
“interval”: 60,
“metrics”: true,
“handlers”: [
“opsgenie”,
“mail_critical”,
“relay”
],
“standalone”: true,
“timeout”: 5
}
}
}

Also sensu-server.log extensions and handler relay.rb is loaded. Still dont see any metrics coming in to Graphite unfortunately.

If not for wizardvan what other possible ways to get data into a time series database for sensu core?
