CA SystemEDGE User Guide › Self Monitoring › Self Monitor Table › Row Creation

Row Creation

The monIndex column of the Self Monitor table acts as a key field (or row index) to distinguish rows in the table. Rows 1 through 10 are reserved for internal use by the SystemEDGE agent. You can configure rows in the range 11 to MAXINT.

You can use the following MIB objects with the Self Monitor table to optimize row creation:

monUnusedIndex

Returns an unused index number for the Self Monitor table when you perform an SNMP Get on the object. Query this object to obtain a number that you can use for row creation.

monMatchDescr

Determines the index number that corresponds to a particular entry description in the monDescr attribute. Perform an SNMP Set on this MIB object with a monDescr attribute value to cause the agent to search through entries in the Self Monitor table and put the index value of the last matching entry in the monMatchIndex MIB object.

monMatchIndex

Matches a particular entry description with its index number when used with monMatchDescr.

You may choose, as a matter of local policy, to reserve a block of rows for system administration. You can then define entries within a reserved block of rows without being concerned that the row may already be taken by another user's entry. In compliance with the local policy, all other users should use row indices outside the reserved range when they define user-configured entries.

By reserving a block of rows, you can define a consistent set of conditions (row entries) to be monitored across all computers such that the same condition is defined in the same row number on each computer. For example, you can use row 31 (monIndex = 31) to define an entry for monitoring the swapCapacity variable, and you can distribute this configuration to every system so that row 31 monitors the swapCapacity variable on every system. The indexes 11 - 16 are used for predefined monitors. The Remote Monitoring AIM uses indexes greater than 8000.

Configuring the agent with CA Virtual Assurance can automate this process. You can configure a block of entries with specific row numbers and deploy that configuration to all managed systems in one operation.
