Monitoring the platform

TODO: faire article ! Indiquer avantages/inconvenient, type de monitoring (hard, services, processings), alert/etat courant, graphes etc...

Managing such a cluster requires some tools to raise alerts when anomalies occur (hardware failures or system issues) but also to investigate current or past state of the cluster. Here are a few tools we use at Cersat.

• Nagios

• Munin (deprecated: pourquoi !?)

• Ganglia

• OpenTSDB

• Homemade tools
