Other Monitoring Methods

Performance Manager supports two additional monitoring methods:

Monitoring from the command line

The following UNIX commands are provided for command-line access to the metrics servers:
Note: The getbulk command uses the SNMPv1 extensions and requires that you access the metrics servers via their private SNMP request ports rather than the well-known SNMP request port. The port to be used is specified by the environment variable PMGR_SNMP_PORT. The appropriate port numbers should be listed in the /etc/services file on the management station.

The following example shows how to query pmgrd using the getmany command: 

% getmany alfred public pm

pmCmSysProcessorType.0 = alpha(2)
pmCmSysOperatingSystem.0 = digital-unix(2)
pmCmSysOSMajorVersion.0 = 3
pmCmSysOSMinorVersion.0 = 2
pmCmSysPageSize.0 = 8192
pmCmSysNumCpusOnline.0 = 2
pmCmSysPhysMem.0 = 262136
pmCmSysPhysMemUsed.0 = 56328
pmCmSysUpTime.0 = 88677120
pmCmSysDate.0 = 7.204.1.17.17.58.57.0.-.8.0
pmCmSysNumUsers.0 = 14
pmCmSysProcesses.0 = 81

pmAoVmSwapInUse.0 = 57160
pmAoVmSwapDefault.0 = /dev/re3c
pmAoVmSiIndex.1 = 1
pmAoVmSiPartition.1 = /dev/re3c
pmAoVmSiPagesAllocated.1 = 256896
pmAoVmSiPagesInUse.1 = 7145
pmAoVmSiPagesFree.1 = 249751
pmAoBcReadHits.0 = 21761200
pmAoBcReadMisses.0 = 78356
pmAoIfEthIndex.1 = 1
pmAoIfEthName.1 = tu0
pmAoIfEthCollisions.1 = 13064347
End of MIB.

Monitoring with SNMP network management systems

You can also use SNMP Network Management Systems (NMS) to access Performance Manager's metrics servers. Examples of commerically available systems include:

Examples of freely available systems include:
Note: The following information is taken from the file /usr/opt/pm/nms/README.nms

Polycenter Netview

  1. Installing and Deinstalling Polycenter NetView Support

    To use PM's NetView support, you should first install Polycenter NetView and Performance Manager on your managment node. Then as super user run the following command:
    /usr/opt/pm/nms/PMGR_Netview_Setup INSTALL

    To uninstall PolyCenter Netview support, run the following as super user:
    /usr/opt/pm/nms/PMGR_Netview_Setup DELETE

  2. Loading PM MIBS

    To make NetView aware of the MIB variables provided by PM's metrics servers, it is necessary to load their associated MIB files into NetView. This is done using the {Options}{Load/Unload MIBs: SNMP...} menu item. The MIB files for PM's metrics servers are listed below, with the metric server name followed by the Polycenter Netview-loadable MIB file:
    pmgrd
    /usr/OV/bin/snmp_mibs/pm-mib.pnv
    clstrmond
    /usr/OV/bin/snmp_mibs/cluster-mib.pnv

  3. Using the NetView MIB Browser Application

    Once you have loaded Performance Manager's MIB files you should be able to browse them using the NetView MIB browser. Note that MIB browers that were opened prior to loading new MIB will not reflect the additional MIB information so you will have to open new ones to get the changes.

    Performance Manager's MIB are found under .iso.org.dec(note that dec appears in at least two places in the OSI naming tree; iso.org.dod.internet.private.enterprises.dec is another well known place). In the NetView browser, click [Up Tree] until you reach org and then go down dec to find the PM MIB variables.

  4. Specifying Private Ports in Polycenter NetView
    Note: If you are running the Digital UNIX extensible agent (snmpd) shipped with Digital UNIX 3.2D (and later), you do not require this section as you are able to access Performance Manager's agents via the SNMP port (UDP/161). The snmpd forwards relevant requests to Performance Manager's agents using the eSNMP subagent supported by Performance Manager's agents.

    Use Options SNMP Configuration... menu item. Earlier versions of Polycenter Netview had a bug in the facility to specify alternate UDP port numbers. The bug was apparently caused by a byte-ordering problem on the UDP port number variable. Following table provides the work around if you are using a version of NetView with this bug. Polycenter NetView versions 4.0 and earlier are known to have this problem.
    INTENDED UDP PORT# ACTUAL VALUE ENTERED
    1161 35076
    1165 36100
    161 41216

  5. Sending SNMP Traps using trapsend(1)

    The script trapsend-example found in this directory is an example of a script that periodically monitors the value of a variable against a threshold value. Upon crossing the threshold value, it sends a trap to NetView. As described in the KNOWN BUGS section of trapsend(1), the script takes care of temporarily setting and then unsetting SR_MGR_CONF_DIR. The Peformance Manager kit installation takes care of setting up the mgr.cnf and snmpinfo.dat in the /etc/srconf/agt directory.

    The script assumes that you are running the extensible SNMP agent (snmpd) that is shipped with Digital UNIX version 3.2D (and later versions).

  6. Sample MIB Applications

    The following sample PNV applications are shipped with this kit. They are installed by PMGR_Netview_Setup and may be accessed from the Monitor->Performance Manager NetView menu.
