Understanding IPM Reports and Graphs

This section explains the various reports and graphs that you generate in IPM:

•System Reports

•Audit Reports

•Real-time Graphs

•Overlay Graphs

•Classification of Statistical Reports and Graphs Based on Granularity

System Reports

Automatically generates statistical reports for collectors based on the report types such as Availability, Latency, Jitter, HTTP, ICMP, PathEcho, RTP and EthernetJitter. 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.

•Minute 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).

•Historical (Hourly, Daily, Monthly, or Weekly) Reports and Graphs

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.

---

Note The older reports are backed up in the prescribed backup folder by running the single backup script available for this purpose, before starting the IPM migration. This script is shipped along with LMS 3.0.

Consolidation of Statistical Data

IPM consolidates the statistical data for all collectors based on the granularity such as Daily, Weekly, and Monthly.

•Hourly to Daily Consolidation

•Daily to Weekly Consolidation

•Daily to Monthly Consolidation

Hourly to Daily Consolidation

The system consolidates the Daily statistical data everyday at 12:30 AM. At the end of every day, the statistical data collected every hour is consolidated and averaged for the day and stored in the Daily table.

For example, 1001.x, where:

•1001—Refers to the Job ID.

•x—Refers to the instances of hourly to daily consolidation.

Daily to Weekly Consolidation

The system consolidates the Weekly statistical data every Sunday at 1 AM. At the end of every week, the statistical data collected every day is consolidated and averaged for the week, and stored in the Weekly table.

For example, 1002.x, where:

•1002—Refers to the Job ID.

•x—Refers to the instances of daily to weekly consolidation.

Daily to Monthly Consolidation

The system consolidates the Monthly statistical data on the first day of every month at 2 AM. At the end of every month, the statistical data collected every day is consolidated and averaged for the month and stored in the Monthly table.

For example, 1003.x, where:

•1003—Refers to the Job ID.

•x—Refers to the instances of daily to monthly consolidation.

---

Note Bad values returned by the source device affects the daily, weekly, and monthly statistical reports. To prevent this, IPM discards the statistics with bad values, such as greater than 999999 or negative values.

---

Understanding System Reports

IPM generates system reports automatically for all collectors based on the report types and granularity after the consolidation of the statistical data. The system reports generated are in tabular format.

You can also generate system reports using the CLI command, ipm generate reports. For more information, see Generating System Reports.

---

Note The system uses applicable collectors for generating the reports. For example, an Echo collector will not be used for generating the UDP Jitter system reports.

---

The system reports are generated for the following granularity:

•Daily—System generates daily reports everyday after the consolidation of Hourly to Daily statistical data.

For more information, see Viewing Daily System Reports.

•Weekly—System generates weekly reports every Saturday after the consolidation of Daily to Weekly statistical data.

For more information, see Viewing Weekly System Reports.

•Monthly—System generates monthly reports at the end of every month after the consolidation of Daily to Monthly statistical data.

For more information, see Viewing Monthly System Reports.

For more information on Hourly to Daily, Daily to Weekly, and Daily to Monthly consolidation, see Consolidation of Statistical Data.

You can delete scheduled report jobs from the Report Job Browser page. However, you can retrieve the deleted jobs from the Report Archives.

You cannot delete system-defined jobs.

To delete the scheduled jobs:

---

Step 1 Go to LMS Portal and select Internetwork Performance Monitor > Reports > Report Jobs.

The Report Job Browser page appears with the list of scheduled report jobs.

Step 2 Select the required report jobs that you want to delete.

Step 3 Click Delete.

A confirmation dialog box appears.

Step 4 Click OK.

Formulae Used in IPM Reports and Graphs

This section explains the various formulae used while generating Minute/Historical reports and graphs See Table 8-44.

Table 8-44 Formulae Used in IPM Reports and Graphs

Report Parameter	Formula
Availability%	(Number of Completions1 / Number of Tries2 ) *100
Error%	(Errors / Number of Tries) * 100
	Latency	Errors=Disconnects+Timeouts+Busies+NoConnections+ Drops+ SeqErrors+VerifyErrors.
	Availability
	PathEcho
	HTTP	Errors=DNS Server Timeout+TCP Connect Timeout+Transaction Timeout+DNS Query Error+HTTP Error+Drops+Busies.
	UDP Jitter	Errors=Internal Errors+Busies.
	ICMP Jitter
	Ethernet Jitter
Standard Deviation formula for RTT	SQRT3 {(Number of Completions * sumSqrdRTT4 ) - (sumRTT5 * sumRTT)} / {Number of Completions * (Number of Completions -1)}
Standard Deviation formula for Jitter	SQRT{(numberofjitter * sumSqrdJitter6 ) - (sumjitter7 * sumjitterj) / numberofjitter * (numberofjitter - 1)}
OverThreshold%	(OverThresholds8 / Tries9 ) * 100
Packet Error%	(Total packet errors / total packets10 ) *100
	UDP Jitter	TotalPacketErrors=LossSD+LossDS+Seq+MIA+Late.TotalPacketErrors=LossSD+LossDS+Seq+MIA+Late.
	Ethernet Jitter
	ICMP Jitter	TotalPacketErrors=PacketLoss+PktOutSeqBoth+PktOutSeqDSes+PktOutSeqSDes+PktLateAS+PacketSkippds.
Average RTT	Sum of round-trip time / Number of Completions.
	HTTP: Average TCP Connect RTT	Sum of round-trip time for DNS query within the HTTP operation / Number of Completions.
	HTTP: Average TCP Connect RTT	Sum of round-trip time for DNS query within the HTTP operation / Number of Completions.
	HTTP: Average Transaction RTT	Sum of round-trip time taken to download the specified object by URL / Number of Completions.
Average Message Body Octets	Sum of size of the message body received in response to HTTP request / Number of Completions.

1 Number of Completions—Number of RTT operations completed without an error or timeout. 2 Number of Tries—Sum of all errors and number of completions. 3 SQRT—Square root. 4 sumSqrdRTT—Sum of square of the round-trip time measured successfully. 5 sumRTT—Sum of the round-trip time measured successfully. 6 sumsqrdjitter: Sum of square of jitter. 7 sumjitter = sum of all jitter. 8 OverThresholds—Number of jitter operations that violate threshold. 9 Tries—Sum of all errors (numDisconnects, numTimeouts, numBusies, numNoConnections, numDrops, numSeqErrors, and numVerifyErrors, and numCompletions). </
