Log Aggregator
You can aggregate the log files of an application service that stops responding or shuts down unexpectedly. You might need to analyze multiple log files to figure out issues with an application service.
You can use the log aggregator to aggregate all the log files associated with an application service and compress required log files into a .zip file. You can download the .zip file and analyze the log files, or upload the .zip file to Informatica Global Customer Support for analysis.
You cannot store the history of aggregated logs. You must download or send the file to Informatica Global Customer Support after you aggregate the log files.
You can aggregate the hang and crash logs of the following application services:
- •Analyst Service
- •Data Integration Service
- •Model Repository Service
In addition to the application service logs, the log aggregator captures debug information for the nodes in the domain. The log aggregator aggregates the log files of the associated application services when you aggregate the log files of an application service. For example, when you aggregate the log files of an Analyst Service, the log aggregator aggregates the log files of the Data Integration Service and the Model Repository Service associated with the Analyst Service.
The log collection directory in the master gateway node stores the application service logs when you aggregate the logs. All the node processes in the domain must have read/write access on the log collection directory. If the node processes cannot access the log collection directory, the aggregated logs do not appear in the aggregated logs listgrid. The core dump directory stores the core dump files of the nodes in the domain. Configure the log collection directory in the master gateway node and the core dump directory for each node in the domain.
When you process the aggregated logs you can choose the collectors from which you want to collect log information. The collectors are application services and nodes associated with the application service.
Aggregating Application Service Logs
You can aggregate log files associated with hang or crash scenarios of an application service.
1. Click the Logs tab in the Administrator tool.
2. Click the Log Aggregator tab.
3. Select the application service for which you want to aggregate the logs.
4. Select the scenario for which you want to aggregate the logs.
You can choose between application service crash and hang scenarios.
5. Select the time interval to aggregate the logs.
You can choose to aggregate the logs from the previous 6 hours to 3 days.
6. Click Next.
7. Select the collectors from which you want to aggregate the logs.
The log aggregator displays the log files and the collectors based on the node to which they belong.
8. Click Finish.
The list of logs associated with the scenario appears in the right pane. You can download the aggregated logs or send the logs to the Informatica Global Customer Support.
Processing Aggregated Application Service Logs
After you aggregate the application service logs, you must download the aggregated zip file or send the logs to Informatica Global Customer Support.
Aggregate the application service logs based on your requirement.
1. Select the logs that you want to process.
2. Click Actions > Compress Logs.
The Compressed Scenario Output dialog box appears.
3. On the Compressed Output tab, click Download to download the aggregated log files as a zip file.
4. Optionally, click the Send to Support tab.
5. Enter the user name, password, and the TFTP directory of the Informatica My Support Portal.
6. Click Send to send the aggregated log files to Informatica Global Customer Support.
