Monyog Disk Monitoring
Low disk space is a critical factor for any application. It can cause the application to perform poorly and make it difficult/unable to install the software upgrades.
Monyog sends SNMP trap/email alerts to all the email-ids if the disk space where Monyog is installed/running is running out. User can free up some disk space before the system goes out of space and shuts down. Thus maintaining high-availability of Monyog.
How to monitor disk space with Monyog?
To monitor the disk space, you will need to set the threshold for the free disk space. Monyog will send email to IDs mentioned under the notification settings of all servers. Alerts will also be sent to email IDs provided in the SMTP settings.
The threshold limit set denotes is for the disk space available in the Data directory of Monyog. In case the installation directory and data directory are stored in different locations, Monyog will alert if the space available to the Installation directory gets below 500MB.
Monyog will monitor the disk space on a 5-minute interval in stable conditions and 1-minute interval when the disk space goes below the threshold value.
The alert notifications will be sent every 6 Hours if the disk space remains below the threshold value.
Server Selector type
There are two options to switch between the behaviour of Server Selector:
Same servers across all tabs If you enable this option, a server selected on one page will make it the default selected server selected across all pages in Monyog (excluding the Overview page). The Overview page will have its own separate server selector applicable only for the page.
Keep them separate This is the default selected option. If you enable this option, a server selected on one page will make it selected only for that page, i.e, each of the pages in Monyog will have its own server selector.
