- any munin-node could support remote or indirect fetching of plugin's data - add support for munin-node:remote-node syntax of host parameter - add process logic to ask for remote node data - displayname should be used to correctly identify such metrics
munin-graphite
Collect Munin statistics, and convert their naming structure to submit to Graphite for visualization.
Requirements
- Munin
- Python
- Graphite (with a Carbon cache or relay)
Installation
Clone the Git repository from https://github.com/jforman/munin-graphite
Example
As of 20130209, the poller is best configured via a Cronjob that runs once a minute.
./m2g-poller.py --muninhost localhost --carbon carbonhost:2004
Metrics paths are created using the hostname and various plugin data. The processes count plugin for Munin would produce metrics and values like the following:
servers.localhost.processes.processes.uninterruptible, value: 0
servers.localhost.processes.processes.processes, value: 224
servers.localhost.processes.processes.runnable, value: 3
servers.localhost.processes.processes.dead, value: 0
servers.localhost.processes.processes.sleeping, value: 221
servers.localhost.processes.processes.zombie, value: 0
servers.localhost.processes.processes.paging, value: 0
servers.localhost.processes.processes.stopped, value: 0
These paths of data are then sent to Carbon via the pickle port.
TODO
Logic will eventually be added to allow the m2g-poller to be run in the background with a list of hosts to query and not require a cronjob.
