IBM AS400 / iSeries

Server snapshot provides an quick overview of current server's auxillary storage pool's usage in percentage, processing units' usage in percentage, permanent address usage in percentage, temporary address usage in percentage and interactive performance usage in percentage.

ASP Usage: The amount of hard disk capacity available in your system is called Auxiliary Storage Pool (ASP). This can be a deceiving number if you have more than one ASP defined on your system, because this number only reflects the System ASP. Applications Manager provides you with the percentage of disk storage in your System ASP that is currently used. If the percentage exceeds 90 percentage the system can fail. The performance of your AS400 server is affected if the percentage usage crosses 80 percent. You can create an alarm for this percentage and alert you whenever the percentage exceeds 80.

Permanent addresses percentage and Temporary addresses Usage: Applications Manager provides you the usage in percentage for the two addresses - Permanent and Temporary Addresses - which refer to the possible system addresses created for permanent and temporary objects in your AS400. Any variation in these values may reflect on rapid changed in the creation or destruction of objects in your AS400 at much rapid pace. This may affect your performance of your server.

Monitor Information

This provides general information about the AS400/iSeries server such as name of the server, current health of the server, type, system model, system serial, and latest polled values. In addition, it also displays system configuration details such as security level, version number, Previous System End, Auto Device Configuration, System Console, Job Message Queue Initial Size, Job Message Queue Maximum Size, Spooling Control Initial Size, Maximum Jobs Allowed, Password Valid Days and Query Processing Time Limit.

Provides the various job counts of various job types currently running in AS400/iSeries server. The information is displayed in a pie-chart with clearly distinction of each job types contribution to total job count. By default, the following services job count is displayed:

• Source PF system

• Spooled Writer
• System
• Spooled Reader
• Subsystem
• Autostart
• Interactive
• Batch

Response Time

Displays the response time of the AS400/iSeries server.

Provides the health of the server. Displays Bar graphs showing the Pool Size, Reserved Size, DB Pages, Non-DB Pages, DB Faults and Non DB Faults.

Job: Specifies the total number of user jobs and system jobs that are currently in the system. It also displays the performance and status information for the active jobs in the system.

Message: Displays the total number of messages received from the server.

Spool: Displays the output of the printer files in the server.

Printer: Displays the number of printer devices connected to the server.

Disk: Specifies the hard disk space utilized by the system.

Problem: Displays the number of problems with ID and description from the server.

Subsystem: Displays the total number of subsystems available under the server.

ASP Percentage

By default, there are four predefined storage pools:

*MACHINE

*BASE

*INTER and

*SPOOL

There are up to 12 user-definable storage pools available.

Pool Size

This displays the amount of memory assigned to each default pools such as *MACHINE, *BASE, *INTER and *SPOOL. You can also edit the amount of memory allocated for each pool by executing the Change Subsystem Description (CHGSBSD) command through Non- interactive Command available in Admin tab. Better allocation would help improve the performance of the server.

Reserved Size

This displays the pool's reserved memory allocation size. The information provided here gives better understanding to how much of the memory allocation has been used by jobs and how much memory is still unused. This reserved size can affect system performance. If insufficient memory is not provided to the default *MACHINE pool, then it can affect overall performance of your AS400 server. Hence monitoring this attribute becomes critical for maintaining better performance of your AS400 server.

This displays the DB and Non DB pages and fault for each pool. This bascially displays how program instructions and database information enter and leave the pool's memory. Monitoring this information provides better visibility on various programs and jobs that are being executed in AS400 server. Applications Manager allows you to monitor the various programs, data queues and configuration objects among others which lets you maintain the overall performance of AS400 server.

Displays the total number of jobs in clear, critical and warning states along with the health of each attribute. You can view jobs in clear, critical or warning state separately by click on the respective counts. For eg, if there are 25 jobs in critical state, the users can view these jobs alone by clicking on the number.

Also, from the pop up window, users can navigate through jobs which are in clea,critical or warning conditions using the Filter By option for the respective monitor. You can also navigate through the For Monitor drop down menu where all the AS400 monitors in APM are listed.

The line graph shows the percentage of jobs in clear, critical and warning condition out of the total number of jobs (a maximum of 2000 jobs are collected from the server).

Displays a wealth of information on various jobs being executed in AS400 server. The user can sort jobs column-wise by clicking on the metric names. Each attribute is explained below.

Batch Job: The user name is specified on the Submit Job (SBMJOB) command, or it is specified in the job description.

Interactive Job: The user name is either typed in at signon or is provided by the default in the job description.

Autostart Job: The user name is specified in the job description referred to by the job entry for the autostart job.

You can enable or disable data collection for a monitor by clicking on the Enable/Disable Job button on the top right hand corner of the Job Details table.

If a user wants to monitor a specific job, they can add job(s) by clicking on the link Add Job(s) to Monitor. Users can also perform actions like END, HOLD and RELEASE from the Actions drop down list and Job(s) can be removed from monitoring by click on the Remove Job(s) link.

Users can configure alarms to each job by click on configure alarm icon and create thresholds for THREADS, PRIORITY, POOL and STATUS of that respective job.

Displays the total number of jobs in clear, critical and warning states along with the health of each attribute. For eg, if there are 10 spool files in critical state and you want to view these spool files alone, you can do it by just clicking on the number.

Also, from the pop up window you can navigate through spooled files which are in clear, critical or warning using the Filter By options for that respective monitor. You can also do the same for other AS400 monitors through the For Monitor drop down menu where all the AS400 monitors in APM are listed.

The user can view spooled files in clear, critical or warning condition in all AS400 monitors by choose 'Show all' in 'For monitor' drop down and navigate through all monitors at a glance.

The line graph shows the percentage of Spooled files in clear, critical and warning condition out of the total number of jobs (a maximum of 2000 jobs are collected from the server).

You can enable or disable data collection for a monitor by clicking on the Enable/Disable Spool button on the top right hand corner of the details table.

The user can sort spools column-wise by clicking on the metric names.

Displays the total number of subsystems in clear, critical and warning states along with the health of each attribute. For eg, if there are 4 subsystems in critical state and the users want to view those subsystems alone, he can do it by just click on the number.

Also, from the pop up window you can navigate through subsystems which are in clear, critical or warning using the Filter By options for that respective monitor. You can also do the same for other AS400 monitors through the For Monitor drop down menu where all the AS400 monitors in APM are listed.

The user can view subsystems in clear, critical or warning condition in all AS400 monitors by choose 'Show all' in 'For monitor' drop down and navigate through all monitors at a glance.

The line graph shows the percentage of subsystems in clear, critical and warning condition out of the total number of jobs (a maximum of 2000 jobs are collected from the server).

You can enable or disable data collection for a monitor by clicking on the Enable/Disable subsystems button on the top right hand corner of the details table.
