Information collection

You can use the JP1/Cm2/Network Node Manager's SNMP protocol to collect information about Datareplicator at each machine.

The JP1/Cm2/Network Node Manager collects and accumulates data from each machine at a specified interval. If numeric data is collected, you can plot a graph to display trends in the number of extracted/imported data items over time. You can also define an event that will issue a warning when a monitored value reaches a specified value. Such information can be used as a basis for automatic monitoring of Datareplicator's status and for issuing a warning if Datareplicator terminates. For details about the Cm2/Network Node Manager's operation, see the manual JP1 Version 8 JP1/Consolidated Management 2/Network Node Manager.

MIB file: There must be a MIB file at each Datareplicator (at the supervisor machine and at each supervised machine) to collect information. Copy a Datareplicator MIB file (the filename is hdsMIB) into the supervisor machine, and then load it with the JP1/Cm2/Network Node Manager. Do not edit a Datareplicator MIB file. For details about the MIB file, see 3.4.9 MIB file.

Organization of this subsection: (1) Mechanism of information collection

The JP1/Cm2/Network Node Manager references the MIB file and issues an object ID and a GET, GETNEXT, or SET request to the supervised machine's SNMP agent. The supervised machine's SNMP agent references the MIB file to return the information that has been collected to the JP1/Cm2/Network Node Manager. When there are multiple Datareplicators in a HiRDB/Parallel Server configuration, information is collected for each machine.

The following figure provides an overview of using JP1/Cm2 for information collection.

Explanation

The supervisor machine's JP1/Cm2/Network Node Manager references the Datareplicator's MIB file (hdsMIB) and passes the object ID and GET, GETNEXT, or SET request code to the supervised machine's SNMP agent.
The supervised machine's SNMP agent references the Datareplicator's MIB file (hdsMIB) and collects Datareplicator information, and then passes the collected information to the supervisor machine's SNMP agent.
The supervisor machine's SNMP agent passes the information to the JP1/Cm2/Network Node Manager.
