To create a new IBM i monitor, follow the steps given below:
There are situations where the host gets automatically discovered with the Monitor running in the host. To disable the default option, disable it using Global Settings.
It is important to note that if Applications Manager server is running in Windows machine, then it can monitor any type of host but if the server is running in Linux, then it can monitor Windows only if an SNMP agent is running in it. Also, any type of user can be used to log into Linux, whereas only Admin users can log into Windows. Learn more about Applications Manager's IBM AS400 Monitoring.
Note: The important configuration details that are required while discovering host resource by Applications Manager are available in Appendix - Data Collection.
The attributes for IBM i monitored are classified under the following tabs by Applications Manager:
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 IBM i 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 IBM i. Any variation in these values may reflect on rapid changed in the creation or destruction of objects in your IBM i at much rapid pace. This may affect the performance of your server.
|System Status||This displays the value and health of ASP percentage, Disk Utilization, Processing Unit percentage, Permanent and Temporary Addresses percentage.|
|History||Displays bar charts showing the Availability History and the Performance History for the last 6 hours.|
|Monitor Information||This provides general information about the IBM i 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.|
|Job Counts||Provides the various job counts of various job types currently running in IBM i 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:
|Disk Utilization||Specifies the hard disk space utilized by the system and updates with the peak and current value, and current status of the Disk Partition parameter.(The parameter includes C, D, E, F drives, etc. in windows, /home, etc. in Linux.)|
|System Information||System information displays the shared processing pool information, uncapped CPU utilization and current processing capacity resources.|
|Memory Utilization||Memory utilization for IBM i is displayed through pool size, reserved size, DB pages and Non DB pages and through DB faults and Non DB faults.|
Under Status tab, Applications Manager monitors the status of various attributes of IBM i server. You can also configure alarms for each of these attributes by clicking on 'Configure Alarms' link.
|System Information||This contains details of your IBM i main storage, number of processors, number of pools, number of partitions and the number of active threads in your system along with the health of each individual attribute.|
|System Status||This displays the value and health of ASP percentage, Disk Utilization percentage, Processing Unit percentage, Permanent and Temporary Addresses percentage.|
|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 IBM i server is affected if the percentage usage crosses 80 percent. You can create an alarm for this percantage and alert you whenever the percentage exceeds 80.|
|Auxillary Storage||The auxillary storage displays ASP total value and health, current unprotected useage and maximum protected usage along with the health of each attribute.|
|Additional Information||Displays information like Current Processing Capacity, Current Interactive Performance Percentage, Shared Processor Pool Used Percentage and Uncapped CPU Capacity Used Percentage.|
|Jobs||Displays the total number of jobs, number of active jobs, number of batch jobs, jobs waiting for messages, and maximum number of jobs in your IBM i server along with the health of each attribute. For number of active jobs, the 7/30 reporting is enabled.|
|Batch Jobs||Displays the number batch jobs ended, ending, held on queue and held while running along with the health of each attribute. It also displays the batch jobs on unassigned job queue and waiting to run/already scheduled jobs in IBM i server. For number of batch jobs on jobqueue, the 7/30 reporting is enabled.|
|Users||Displays the values for total number of users signed on and signed off, along with users suspended by group jobs, users suspended by system request and users temporarily signed off. For number of users signed on, the 7/30 reporting is enabled.|
Under Pool tab, Applications Manager displays pool details for the IBM i server. Applications Manager provides you in-depth details for Pool such as Pool Name, Pool Size, DB pages, DB faults, Non DB pages and Non DB faults. The health and alarm configuration for each corresponding attribute is also provided. Click on the metric names (say Pool Name, Pool Size or DB pages) for column-wise sorting.
You can enable or disable data collection for a monitor by clicking on the Enable/Disable Pool button on the top right hand corner of the Pool Details table. In the Performance Polling Settings window that pops up, un-check the metrics that you need to disable and click Apply to save the settings. You can also apply the same settings to other IBM i servers by clicking on Apply to Selected Monitors link.
|Pool Name||Name of the pool. 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 IBM i server. Hence monitoring this attribute becomes critical for maintaining better performance of your IBM i server.|
|DB and Non DB Faults and Pages||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 IBM i server.|
Under Jobs tab, Applications Manager monitor Jobs status and health in detail. You can easily configure alarms for Job details by clicking on 'Configure Alarms' link. The table consists of the following columns:
|Job Summary||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 clear, 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 IBM i 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. The number of jobs collected from the server is set to 100 by default, which can be changed by the user by changing the values in AS400Server.properties file.|
|Job Details||Displays a wealth of information on various jobs being executed in IBM i server. The user can sort jobs column-wise by clicking on the metric names. Each attribute is explained below:
|Job Name||The name of the job as identified by IBM i.|
|User||The user name is the same as the user profile name and can come from several different sources, depending on the type of job.|
|Number||The system-assigned job number.|
|Type||The type of active job. Possible values are:
|Status||This displays the status of the initial thread of the job. Only one status is displayed per job. The status 'NONE' represents an initial thread that is in transition.|
|Pool||This displays the system-related pool from which the job's main storage is allocated.|
|Function||This displays the last high-level function initiated by the initial thread. This field is blank when a logged function has not been performed. The field is not cleared when a function is completed.|
|Priority||This displays the run priority of the job. A lower number indicates a higher priority. System jobs and subsystem monitors with a run priority higher than priorities allowed for user jobs show a priority of 0. Run priority ranges from 1 (highest) to 99 (lowest). Jobs with the highest priority receive the best service from the CPU. This value is the highest run priority allowed for any thread within the job. Individual threads may have a lower priority.|
|Threads||Displays the number of active threads in the job.|
|Queue||Displays the name of the Queue where the job is located.|
|Subsystem||The name of the subsystem that holds the job.|

The job status in IBM i is classified into three types:
1. Jobs Clear
2. Jobs Warning
3. Jobs Critical
If you would like to define a particular job status as critical, edit AS400server.properties in AppManager Conf directory and include the particular job status as critical.
Open the conf file in the Applications Manager directory:
Windows: C:\Program Files\ManageEngine\<AppManagerHome>\conf
The file consists of jobs in pre-defined classification under clear, warning and critical categories. If you would like to include a particular job status say for example CMNA as critical, add CMNA in the following line as follows
am.as400.critical = MSGW, CMNA
Save the file and restart Applications Manager. After the next polling interval, you will find that the particular job is now classified as a Critical job status.
Message Information display gives you more detailed information about the various message(s) being received in the message queue (By default we are monitoring 'QSYSOPR' message queue, but user can change this value for key 'am.as400.messagequeue' in AS400Server.properties file'). The messages are displayed with in-depth details such as message ID, severity of the message, type of the message, message text with a cause and recovery information if applicable, date and time of the message generated and help information for that particular message. You can view more detailed information of a particular message by clicking on the Help icon - .
By default only messages that need a reply are displayed. To view all the messages click on the link Show all messages. From the pop-up window that appears, the user can also view filter messages by Messages Need Reply / All Messages. This can be done for a specific monitor or for all IBM i monitors from For Monitor drop down menu.
The number of messages collected from the server is set to most recent 100 messages by default, which can be changed by the user by changing the values in AS400Server.properties file. The user can create thresholds for 'Messages' and configure alarms for MESSAGE ID, SEVERITY, and MESSAGE to capture the critical messages.
The user can sort messages column-wise by clicking on the metric names:
