The devCapacity column of the Device table shows the percentage of file system space used. Use the devCapacity column to check if the file system space usage is full.
Use the Self Monitor table to instruct the agent to monitor the devCapacity values and send traps to the management system if the devCapacity value breaches the threshold value. For example, use the following directive to configure the agent to monitor the /usr directory and send a critical state change trap if the usage capacity of the /usr directory is more than 90%:
monitor 11 0x00 60 absolute > 90 'Monitor device space usage' '' devTableEntry '/usr' devCapacity
For more information about setting thresholds, see the chapter "Self Monitoring.”
