XtremIO EMC Storage Monitoring with NetEye
If you need to monitor a Dell EMC Storage XtremIO unit, then I have the right solution for you. Not long ago, I wrote an XtremIO storage tracking plug-in that can execute the following activities:
- XTREMIO_CTRL_Status: monitors the controllers and the hardware status
- XTREMIO_DPG_Status: controls the DPG groups from the storage array
- XTREMIO_Storage_Efficiency: verifies and displays the actual XtremeIO “deduplication and compression” efficiency
- XTREMIO_Storage_Space: checks the available storage space
But how does it work?
Here’s the link to get the XtremIO monitoring plug-in . The monitoring procedure works using the XtremeIO EMC’s REST API. All you need is to create a new user, which you can do by creating a username and password via the Web-Frontend. The archive contains the plug-in, a PHP file for pnp4nagios, and a service profile for Monarch (NetEye Monitoring Configuration Frontend).
If you use NetEye, then it will be quite simple to implement this solution. You just need to:
- Copy the plug-in file (check_xtremio) into the directory /usr/lib/nagios/plugins of NetEye Servers
- . The Profile files are downloadable from the link on the Blog and have to be unzipped on your PC and then uploaded from there with the “Upload” button on the Monarch > “Profiles” > “profile Importer” form. The files are in XML format.
By following the steps above you can add the following service checks:
- XTREMIO_Cluster1_Dedup_Ratio: controls the Cluster1 LUN deduplication
- XTREMIO_CTRL_Status: checks the controllers’ status
- XTREMIO_DPG_Status: monitors the Data Protection groups’ status
- XTREMIO_Storage_Efficiency: checks the data storage compression and deduplication efficiency
- XTREMIO_Storage_Space: verifies the storage level
There are also other useful commands:
- Registering and monitoring a specific API value:
/usr/lib/nagios/plugins/check_xtremio -H <host> -U <user> -P <password> -T command -K types/clusters/1 -f dedup-ratio -t dedup-ratio-text
- Controller state
/usr/lib/nagios/plugins/local/check_xtremio -H <host> -U <user> -P <password> -T ctrlstate
- Storage space usage: (Warning on 95% and Critical on 98%)
/usr/lib/nagios/plugins/check_xtremio -H <host> -U <user> -P <password> -T storage-space -w 95 -c 98
By installing this plug-in you can get your XtremIO Storage completely under control.
