LizardFS is a high performance distributed storage system for storing massive amount of data on commodity hardware. OddEye Agent uses LizardFS's built in tools to expose statistics and send to OddEye servers. You just need to set hostname of target server and chose detalization of metrics.
Install
cd ${OE_AGENT_HOME}/checks_enabled
ln -s ../checks_available/check_lizardfs.py ./
Configure
Configuration parameters of LizardFS check are in ${OE_AGENT_HOME}/bonf/bigdata.ini file
[LizardFS]
host: 127.0.0.1
port: 9421
chunkstats: True
diskstats: True
Host and port parameters points to master node. It's always a good idea to run OddEye Agent on target hosts, so for most of installtions these parameters can stay defaults.
Other parameters enables and disabled detailed statistics of chunk servers, and disks|mountpoits
Restart
${OE_AGENT_HOME}/oddeye.sh restart
