Gathering PATROL data from PATROL MIB tables

The PATROL Agent MIB consists of several dynamic tables that allow you to navigate PATROL KM parameter data collected using SNMP get operations. However, the dynamic nature of object IDs make it difficult to poll for some applications. Using a separate values table with the parameter name allows more static access to the same parameter data.

Using an SNMP get operation, it is possible to obtain many attributes of a parameter, instance, or application class object. Following are some of the attributes:

• Parameter value — SNMP get on the "value" variable of a parameter name
• Parameter status — SNMP get on the "status" variable of a parameter name
• Parameter last set time — SNMP get on the "time" variable of a parameter name
• Instance status — SNMP get on the "status" variable at instance level
• Application class status — SNMP get on the "status" variable at class level

See Changing-variables-manually for more information about tables that map PATROL managed objects to SNMP MIB variables.
