[PYTHON] [blackbird-xfs] Monitor xfs with blackbird

A little strange story It is an example that you can use it not only for middleware but also for this kind of usage.

blackbird xfs plugin

This plugin gets various information from / proc / fs / xfs / stat and sends the data to the backend

read/write bytes

read statistics

transaction&log statistics

write statistics

You will be able to take such a graph

The contents of / proc / fs / xfs / stat are like this

/proc/fs/xfs/stat

I think it's information that you don't usually see, but it may be useful to monitor it.

Install

blackbird body

Please install by referring to here

Install xfs plugin

You can either use setup.py or rpm.

install with setup.py

git clone https://github.com/Vagrants/blackbird-xfs.git

install with rpm

yum install blackbird-xfs --enablerepo=blackbird

Set plugin

The config is in /etc/blackbird/conf.d/xfs.cfg, but usually there is nothing to mess with.

ini:/etc/blackbird/conf.d/xfs.cfg

[xfs]
module = 'xfs'

The default monitoring interval is 60 seconds, but if you want to change it

ini:/etc/blackbird/conf.d/xfs.cfg

interval = 30

Please specify as

Reboot blackbird when you're done

sudo /etc/init.d/blackbird restart

Check if data is coming in on Zabbix

Zabbix Templates can be found in the github repository Please import to Zabbix and apply to the target server

** If the host name on Zabbix and the host name of the server on which blackbird is running are different, you need to set the hostname on /etc/blackbird/conf.d/xfs.cfg ** Please match with Zabbix

ini:/etc/blackbird/conf.d/xfs.cfg

hostname = your_static_hostname

• Honestly, I did my own kernel research to find out what each value of / proc / fs / xfs / stat means, but I'm not very confident.
• I would like an expert to tell me what value to look at when looking at xfs performance and bottlenecks.
