Monitoring System Resources

System Monitor Reference

 

Filesystem Available Space

 

The filesystem monitor checks the number of megabytes available for use in each

 

file system on the node. File systems must be mounted and active to be monitored.

 

File systems mounted over the network, such as NFS file systems, are not

 

monitored.

 

The MIB variables fileSystemBavail, and fileSystemBsize from the

 

hp-unix MIB are used to calculate the number of available Kb in the file systems.

 

The number is then divided by 1024 to get the number of available Mb.

Resource Name

 

 

 

 

 

Most common names are:

 

 

/system/filesystem/availMb/stand

 

 

/system/filesystem/availMb/root

 

 

/system/filesystem/availMb/home

 

 

/system/filesystem/availMb/opt

 

 

/system/filesystem/availMb/tmp_users

 

 

/system/filesystem/availMb/usr

 

 

/system/filesystem/availMb/var

 

 

 

 

You may have more file systems, or different names, depending on how you

 

configured file systems on your system. You can monitor when a file system starts

 

filling up so you can clean up old files or add disk space and reconfigure your file

 

systems.

 

 

 

NOTE

Because the “/” character is not valid in a resource name, it is replaced by the “_”

 

character. So the file system /tmp/users would appear as the resource name

 

/system/filesystem/availMb/tmp_users. For the same reason the root file system (/)

 

is replaced by the name “root”.

 

The minimum polling interval is 30 seconds. We recommend a longer interval; short

 

 

polling intervals may adversely affect system performance.

 

When configuring requests from the SAM interface, a wildcard (*) is available to

 

monitor all file systems on a system.
