Information that OnSNMP provides
All the information that OnSNMP provides is available from other sources, such as the system catalog tables, the sysmaster and sysutils databases, dbaccess calls, and the onstat utility.
However, the system catalog tables and the onstat utility
refer only to a single database, and the sysmaster and sysutils databases
refer only to a single database server. OnSNMP provides information
that lets an SNMP Network Manager monitor all the HCL Informix® databases that
are on a network. The following figure illustrates this concept.
