OX Imageconverter Monitoring

General

The Open-Xchange JMX offers the ability to fetch runtime information of the Java virtual machine, and about the Open-Xchange Middleware (aka groupware backend) including Imageconverter.

For general information about the JMX interface see: OX_monitoring_interface

The usage of Jolokia to access monitoring data is described in the article Jolokia

Plugins are available for integration in the munin monitoring framework: OX_munin_scripts

OX Imageconverter

Monitoring data for Imageconverter can be obtained after installation of the packages open-xchange-munin-scripts-jolokia and open-xchange-imageconverter-monitoring. It uses Jolokia if available and configured.

Here is a list of Imageconverter sample data provided by

# /opt/open-xchange/sbin/showruntimestats --port 9995 -I
MedianKeyQueueTimeMillis_Background = 0
RequestCount_Total = 20
CacheHitRatio = 0.0
RequestCount_Get = 10
RequestCount_CacheAndGet = 10
RequestCount_Cache = 0
MedianKeyQueueTimeMillis_Instant = 0
CacheKeyCount = 9
RequestCount_Admin = 0
MedianRequestTimeMillis_Total = 0
MedianKeyQueueTimeMillis_Medium = 0
MedianKeyQueueTimeMillis_Total = 0
PeakKeyCountInQueue_Background = 0
PeakKeyCountInQueue_Medium = 0
PeakKeyCountInQueue_Instant = 0
MedianRequestTimeMillis_Get = 0
KeysProcessedCount = 10
CacheSize = 9670276
MedianKeyProcessTimeMillis = 466
MedianRequestTimeMillis_Admin = 0
MedianRequestTimeMillis_CacheAndGet = 0
MedianRequestTimeMillis_Cache = 0

OX Imageconverter and munin

The Imageconverter uses a different port to provide monitoring data via Jolokia. The corresponding oxJolokiaURL has to be configured with an entry in the settings.

[ox_imageconverter*]
env.oxJolokiaUrl http://localhost:8005/monitoring/jolokia
