Log file uses and advantages• Logs record the time and severity of errors, warnings, and other system

events

• Logs are useful for monitoring, troubleshooting, and performance analysis

• You can add and edit new log files to meet your needs

– Create a log file to monitor warning messages generated by a specific user using a certain business process

Log file disadvantages

• Time consuming and cryptic

- Going through thousands of lines to find the 2 or 3 that matter.

• In the past there was no way to search the log file for ONLY those lines that relate to a user’s business action

• It is difficult to get to the log after receiving an error in the UI

– Some actions did not provide a direct link to the logs. Therefore, the user had to navigate to the log page, and search for their information

Where to Create and Modify Logs

Go to Configuration and Administration> Power Data->General->Log File

Types of Logs

• Ad Hoc – logging selective business processes like integration, or bulk planning

• System – logging events throughout the system

• User – logging events pertaining to a specific user

• Web – for controlling web server logging.

How to Create a New Log

1. Give the log a Log ID

2. Specify what type of log

3. Give it a file name

4. Mark the Append and type a

Max Size in bytes for the file

5. Check to Turn On the Log

6. Using the Left and Right blue

arrow buttons move the log ID’s

you want to enable

7. Click Finished

How to View the Log

1. Under each Manager you can click Process Manager >

System to be taken to the screen shown here

2. Enter a date and time From which the log is to begin. The

time auto displayed is exactly 120 seconds before you

clicked System to view this screen

3. Select the type of Log:

4. Select one or more Severities:

5. Select one or more IDs of business processes to be logged.

6. To find a particular item or name, type the name in the

Search For field. This is like a Grep command

7. If you do not want your search to be case sensitive click

Ignore Case

8. Each activity in OTM is given a Top Level Process ID. If you

know the ID you can constrain logs to just 1 process

9. If needed, change the number Entries per Page to appear

in the log. 100 is the default and 1000 is the max.

10. Based on how the Log is configured you can search backup

files

How to View the Log cont’d

1. Save to File allows you to export your log to a text file

2. Max to Save (in KB) is the max export log size. The default

is 100kb but max is 5000kb.

3. Click View Results. Or click Reset to enter new values.

Notes: Use the Top Level Process to constrain what log content

you see. If you do not know your Top Level Process ID use

the Search For to find it. You can use the Gid of the object

your were working with to search for.

Use the Save to file feature and always set Max to Save to 5000.

It will guarantee you get as much log as possible.

Log Content – Tricks of Trade

When troubleshooting an error start at the error and work your way backwards. Many of times the source of the issues can be found near the error.

Milestones in the log are separated by the following asterisk lines
