IPM Reports and Graphs
This section explains how to generate minute reports and graphs, historical reports and graphs, audit reports, and system reports.
It contains the following topics:
•
Understanding IPM Reports and Graphs
•
Understanding IPM Reports and Graphs
This section explains the various reports and graphs that you generate in IPM:
•
System Reports
Automatically generates statistical reports for collectors based on the report types such as Availability, Latency, Jitter, HTTP, ICMP, PathEcho, and RTP. The system reports are generated on a daily, weekly, and monthly basis.
For more information, see Understanding System Reports.
Audit Reports
Tracks and reports the configuration changes on the IPM server performed by the LMS users.
For more information, see Audit Reports.
Real-time Graphs
Captures the statistics of a configured collector that polls in real time. This statistics appears in real time and is not stored in the IPM database. You can view the real-time graph for Collector types such as Historical/Statistical and Monitored/Real-Time.
However to do this, the collectors must be in Running status for both the collector types. You can monitor the statistics of more than one collector at a time.
For more information, see Monitoring a Collector.
Overlay Graphs
Compares the latency of the collectors based on the granularity. However, for comparing the graphs, the collectors you select must be in Running, Completed, Dormant, or Stopped status.
For more information, see Viewing Collector Graphs.
Classification of Statistical Reports and Graphs Based on Granularity
Based on the granularity specified, you can generate either Minute or Historical reports and graphs.
•
Generate statistical data for a single or a group of collectors on a minute basis. You can generate Minute reports and graphs for collectors only if you have set the polling interval time in minutes (such as 1, 5, 15, 30) while creating collectors. You cannot generate Minute reports and graphs if the polling interval is set to 60 minutes (Hourly collectors).
•
Generate statistical data for a single or group of collectors based on the granularity such as hourly, daily, monthly, or weekly. You can generate Historical reports and graphs irrespective of the polling interval specified while creating collectors.
For more information, see Working with Minute/Historical Reports and Graphs.
While migrating from IPM 2.6 to IPM 4.0, the database of IPM 2.6 also gets migrated. However, this database contains only the statistical data that are within the purge period specified.
Example: If the purge period for daily granularity was specified as six months, the database contains data for only six months. The data or the reports older than six months are not available. The older reports are backed up in the folder specified when Single backup script, shipped with LMS 3.0, was run before starting the IPM migration.
Working with Minute/Historical Reports and Graphs
This section explains how to generate minute or historical reports and graphs for the following report types based on the granularity such as minute, hourly, daily, weekly, and monthly.

•
Availability Reports and Graphs

Audit reports track all the configuration changes on IPM server performed by the LMS users.
You can also track the changes performed by the IPM server with the username IPM. As IPM server updates the IPM device space whenever a device gets added/edited/deleted in DCR if the Automatically Manage Devices from Credential Repository option is selected on the Application Settings page (Admin > Application Settings).
To view the list of IPM tasks that trigger an Audit report, see IPM Tasks With Audit Reports.
You can perform the following tasks on the audit reports:
You can track the changes that are performed on the IPM server.
You can purge the audit reports.
IPM Tasks With Audit Reports
An Audit report is triggered and logged when you perform the following IPM tasks:
Generating Audit Reports
You can generate audit reports on all Audit changes that occurred in the network during a specified time period.
Note
To generate Audit reports:
Step 1
The Audit Reports page appears.
Step 2
Step 3
The Audit Reports window appears. See Table 8-32 for more information.
Audit reports contain all change information provided by IPM modules based on your filter criteria. It contains the following fields.
Purging Audit Reports
You can set the purge period for audit reports on the Purge Settings page. After you set the purge period, the audit reports that are greater than the set purge period are purged. This frees disk space and maintains your audit reports at a manageable size.
Note
To purge the audit reports:
Step 1
The Purge Settings page appears.
Step 2
The audit reports older than the number of days you specify will be purged. The default purge period is 180 days.
Step 3
Using Report Archives
You can manage the archived reports and create report jobs on the Historical Reports page (Internetwork Performance Monitor > Reports > Report Archives).
See Table 8-33 for more information.
Using the Filter field on the Historical Reports page, you can filter the archived reports based on your requirement. You can filter the archived reports using one of the following filter criteria and clicking Filter:

Generating Statistical Reports and Graphs
IPM allows you to generate statistical reports and graphs based on the report types (such as Availability, Latency, Jitter, ICMP Jitter, HTTP, and PathEcho and the granularity (such as Minute, Hourly, Daily, Weekly, Monthly).
Based on the granularity specified, you can generate either Minute or Historical reports and graphs for each report types. However for the report types Availability and Path Echo you can only generate Historical reports and graphs.
For more information on the Minute and Historical reports and graphs, see Working with Minute/Historical Reports and Graphs.
You can generate the Minute or Historical reports and graphs either immediately or schedule them to run at a specified time.
For more information, see Immediate Reports and Graphs or Scheduled Reports and Graphs.
Immediate Reports and Graphs
The Immediate reports and graphs are generated instantly and are not stored in the Report Archives. You can set this option while creating the report jobs.
