Using EMS HA Monitors

Chapter 5 71
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.
Table 5-3 Filesystem Available Space
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.
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
