• Self management

Managed Component, MCConcept of Managed Components

The “Managed Component”, MC, is a “Managed Object”, i.e. an entity that is manageable.

The MC is a set of one or more processes.

One process can not exist in several MCs.

The MCs is the smallest logical entity a system administrator has to manage.

Self Management Service

The following services are covered by self-management:

Start/Stop/Restart Start, Stop and Restart MCs

Product Inventory To see what is installed in the O&M system.

System Logging Logging of normal system events in the O&M system.

Error Handling Logging of abnormal system events in the O&M system.

Alarms Generate alarms from errors.

SW Trace Start, stop and collect debugging printouts in O&M applications.

Self Test Perform self-tests on MCs.

Instrumentation Get run time values, e.g. queue length.

Configuration Handling of configuration parameters.

Self Management CLIIf and when it is impossible to start a graphical user interface you can also control most self management features from a command line interface:

#/opt/ericsson/nms_cif_sm/bin/smtool

( Nowdays ’smtool’ is in $PATH )

Using this tool you can for example:

•View status of MCs•Start/Stop/Restart MCs•Display/Set configuration parameters•Start/Stop CIF Trace for MC[s]

You might also want to take a look at a similar unofficial tool:

#/opt/ericsson/sck/tmp/ssr.sh

Self Management CLIsmtool command examples:

smtool list Lists status off all MCssmtool list | grep –v started Lists not started MCssmtool offline sdmsmtool online sdmsmtool warmrestart eam_handlerMtp Re-reads MC / process configurationssmtool coldrestart FM_DistributionServer Same as offline + onlinesmtool trace ARNEServer 1-199 arne_trace.log smtool trace <MC> <trace type> <file>smtool trace stopsmtool cancel Cancels ongoing start/stop of MCs

What is SMIA ?

• SMIA – Statistical Initiation and Administration Tool

• SMIA is an tool which facilitates Initiation and Administration of statistical measurements towards Network Elements built on the AXE platform

• Part of the performance management suite of

Command Description

Daily Tasks

# uptimeCheck the Server’s uptime on daily basis to verify that whether it has been rebooted without the administrator’s knowledge.

# iostat -E Verify that all the physical disks or disk arrays are having any Soft Error, Hard Errors or Transport Errors.

# /usr/platform/sun4u/sbin/prtdiag –vVerify that all the system components, like CPU, Amount of Cache, Cooling FAN, Power Supplies etc., are working properly.

# vmstat By means of the UNIX command `vmstat' it is possible to identify if a performance problem is caused by a shortage of memory or CPU power.

# prstatUse the following command to monitor which application/process is using the CPU resource most. It is a real time CPU monitoring sun command.

# tail –1000 /var/adm/messages | moreLogically read the system generated administrative message which gives the information for the successes and failures occurred during operation. Very useful for troubleshooting.

# df –k To determine the amount of disk space available and used on the file system.

# du –kCheck the amount of disk space in number of 1 Kbytes blocks used by the current directory and subdirectories if you have space problem for file systems.

# vxprint Check the Status of the Disks Under Veritas Control, all disks must show Okay status.

# vxdisk list Check the status of mirroring.

# vxprint –p  

# vxprint –ht  

# /opt/ericsson/nms_cif_sm/bin/smtool listCheck that all processes are running in CIF Management Console. Open the CIF Management console and observe that all the processes are online.If offline, make them as online.

# /opt/versant/ODBMS/bin/dblist Check the status of the versant databases whether it is active or not.

# more /var/opt/ericsson/sdm/log/SDM_GRAN_dispatcher.log Read SDM error reports messages for statistics data missing & other messages.

# cd /var/opt/sybase/sybase/log Check the Sybase error log

# /ericsson/syb/util/db_check.sh Check database space.

# isql –Usa – w2000 –Psybase11 1> sp_helpdb 2> go

Check None of the Databases should be Offline.

# df –kh /ossrc/sybdev/sybmaster# df –kh /ossrc/sybdev/pm/pmsybdata# df –kh /ossrc/sybdev/pm/pmsyblog# df –kh /ossrc/sybdev/oss/syblog# df –kh /ossrc/sybdev/fm/fmsyblog# df –kh /ossrc/sybdev/fm/fmsybdata# df –kh /ossrc/sybdev/oss/sybdata

Check Remaining disk space on sybase filesystem.

# cd /var/opt/ericsson/sgw/outputfiles/apg40files/sts Observe the latest time stamp of the files coming from APG40.

# isql –Usa –w2000 –Psybase111> use bsddb2> go1> select max(TIME), NE from CELL_ADM where RES=1 group by NE2> go

Verify that the STS data coming from the nodes are getting loaded properly in the database/Sybase for each of the active nodes
