Logging

All Event processing logs can be found at below path. This have event spy logging information also, if enabled.

<DCF-Install>/Collecting/Collector-Manager/<INSTANCE>(ex:smarts-metrics-collect)/logs/collecting-0-0.log

Note: Latest processing log name will have "-0-0" appended to its name like above.

To enable logging, change the collecting configuration to push metrics/topology data to file connector like below. And after changing the configuration, operator need to restart the service to see the logging info in collecting-0-0.log.

Edit below file as specified:

File : <DCF-Install>/Collecting/Collector-Manager/<INSTANCE>(smarts-metrics-collect)/conf/collecting.xml
---
<connector enabled="true" name="File" type="File-Connector"   config="conf/file-connector.xml" />

---

For example : "smarts-metrics-collect" is installed management pack name in the below example:

To check the status of the installed services:

<DCF-Install>/bin/manage-modules.sh service status all
….
* Checking collector-manager smarts-metrics-collect'...       [ running ]

To restart the particular service:

<DCF-Install>/bin/manage-modules.sh service restart collector-manager smarts-metrics-collect
 * Stopping collector-manager smarts-metrics-collect'...            [ OK ]
 * Starting collector-manager smarts-metrics-collect'...            [ OK ]
