SLLogCollector

SLLogCollector is a tool that can be used to easily collect log information and memory dumps from a DataMiner Agent. Log collection can be very useful to troubleshoot issues in DataMiner.

This log collector tool is available on every DMA from DataMiner 10.0.5 onwards. It is located in the folder C:\Skyline DataMiner\Tools\SLLogCollector.

From DataMiner 9.6.0 [CU23], 10.0.0 [CU13], 10.1.0 [CU2] and 10.1.5 onwards, you can also access SLLogCollector from the shortcut menu of the DataMiner Taskbar Utility. To do so, right-click the taskbar utility icon and select Launch > Tools > Log Collector.

If SLLogCollector is not installed on your DataMiner Agent, you can download it from DataMiner Dojo.

Note
  • This tool requires .Net Framework 4.8 or higher.
  • If our tech support team has requested that you run this tool, they will also provide a link to a secure SharePoint site where you can upload the resulting package.

Running the tool

To use the SLLogCollector tool:

  1. In the folder mentioned above, double-click SL_LogCollector.exe.

  2. From DataMiner 10.1.0 [CU11]/10.2.2 onwards, optionally, create a CollectorConfig XML file to fine-tune which resources are collected. See Using a custom CollectorConfig XML file.

  3. Configure the necessary options:

    • To only collect logging for the period since DataMiner was last started, select Exclude logging of previous run of DataMiner.

    • To collect memory dumps as well as logging, select Include memory dump. Then select for which process(es) memory dumps should be collected and when these should be collected.

      Note

      When you select the option to collect memory dumps and one or more run-time errors are present, processes affected by these run-time errors are automatically selected.

    • Use the radio buttons to select the location where the log package will be saved. By default, logs are saved to %USERPROFILE%\Desktop\SL_LogCollector.

  4. When the configuration is complete, click Start.

    Note

    If you just want to use the default settings and save the package to your desktop, there is no need to configure any of the options mentioned in the previous step. All you need to do is click the Start button. In case of RTEs, memory dumps are included automatically.

  5. To view information on the actions of the tool, expand the Console section at the bottom of the window. For more detailed information, click the Show detailed log button.

Note

From DataMiner 10.3.3/10.4.0 onwards, each time the SLLogCollector tool is run, it will order the Standalone BPA Executor tool to execute all BPA tests available in the system. The files containing the test results will have names using the <BPA Name>_<Date(yyyy-MM-dd_HH)> format and can be found in the C:\Skyline DataMiner\Logging\WatchDog\Reports\Pending Reports folder.

Running the tool via command line

From DataMiner 10.1.11/10.2.0 onwards, you can also run the tool via command line, using the options listed below.

Option Description
-c
--console		 Runs the console version of the tool. Always specify this option if you want to run the tool via command line.
-h
-?
--help		 Shows help.
-f=VALUE
--folder=VALUE		 Determines the folder where the logging should be saved. Default: C:\Skyline_Data\
-d=VALUE
--dumps=VALUE		 Allows you to specify the process names or IDs for which dumps should be taken. "VALUE" should be a comma-separated list of names or IDs.
-m=VALUE
--memory=VALUE		 If this option is added, an additional dump will be taken after the process reaches the amount of memory (in MB) specified as "VALUE".

For example:

SL_LogCollector.exe -c -d=25784,2319
SL_LogCollector.exe -c -h
Note

From DataMiner 10.3.3/10.4.0 onwards, each time the SLLogCollector tool is run, it will order the Standalone BPA Executor tool to execute all BPA tests available in the system. The files containing the test results will have names using the <BPA Name>_<Date(yyyy-MM-dd_HH)> format and can be found in the C:\Skyline DataMiner\Logging\WatchDog\Reports\Pending Reports folder.

Using a custom CollectorConfig XML file

From DataMiner 10.1.0 [CU11]/10.2.2 onwards, you can use a custom CollectorConfig XML file to indicate which resources need to be collected. This file should be placed in the folder C:\Skyline DataMiner\Tools\SLLogCollector\LogConfigs. By default, this folder will contain a Default.xml file, listing a default list of resources to be collected.

Note

From DataMiner 10.2.0 [CU11]/10.3.2 onwards, instead of in the default folder C:\Skyline DataMiner\Tools\SLLogCollector\LogConfigs, you can place the custom CollectorConfig XML file in a LogConfig folder within the same folder as SL_LogCollector.exe.

To customize the collected resources, add your own custom XML file to this folder, specifying the "collectors" that should be used.

Here is an example of such a configuration file:

<ResourceCollectorConfig>
   <Collectors>
      <File name="Collector1">
         <Source>C:\Windows\System32\LogFiles\Apache</Source> <!--Search in this folder-->
         <Destination>Cassandra\Apache</Destination> <!--Place the results here-->
        <Patterns>
           <Pattern amount="1">cassandra-stderr*</Pattern> <!--take the most recent cassandra-stderr*-->
           <Pattern amount="1">cassandra-stdout*</Pattern> <!--take the most recent cassandra-stdout*-->
           <Pattern amount="1">commons-daemon*</Pattern><!--take the most recent cassandra-daemon*-->
        </Patterns>
      </File>
      <Http name="Collector2">
         <Source>http://127.0.0.1:8222</Source> <!--The host info-->
         <Destination>NATS\APICalls</Destination> <!--Relative path to save the result file-->
         <Endpoints>
            <Endpoint name="connz"> <!--An endpoint named connz that will be contacted-->
               <Requests>
                  <Request>subs=detail&amp;sort=bytes_to&amp;auth=1</Request><!--a query to send to connz-->
               </Requests>
            </Endpoint>
            <Endpoint name="routez"> <!--An endpoint named routez that will be contacted-->
               <Requests>
                  <Request></Request> <!--empty request-->
               </Requests>
            </Endpoint>
         </Endpoints>
      </Http>
      <Exe name="Collector3">
         <Source>C:\Program files\Cassandra\Bin</Source> <!--The location of the executable-->
         <Executable>nodetool.bat</Executable> <!--The executable-->
         <Destination>Nodetool</Destination> <!--The relative path to save the result-->
         <Commands>
            <Command>status</Command> <!--A command called status to be passed to the executable-->
            <Command>cfstats</Command> <!--A command called cfstats to be passed to the executable-->
         </Commands>
      </Exe>
   </Collectors>
</ResourceCollectorConfig>

In this example, three collectors have been defined, each of a different type:

  • Collector1 is a collector of type "File" and will order SLLogCollector to retrieve a set of files (e.g. log files).

  • Collector2 is a collector of type "Http" and will order SLLogCollector to send an HTTP request to a server and to store the response.

  • Collector3 is a collector of type "Exe" and will order SLLogCollector to run an executable file and to store the output.

Collectors of type File

Collectors of type "File" can be used to retrieve files matching a specific pattern. You can configure them using the following XML elements and attributes:

Element/attribute Type Mandatory Description
File@name String Yes The name for the collector.
File.Source Yes The folder in which SLLogCollector will search for files and folders.
File.Destination Yes The (relative) path to the destination folder in the archive.
File.Patterns Yes The element containing all search patterns.
File.Patterns.Pattern Yes A Microsoft .Net search pattern to filter file names or file paths.
File.Patterns.Pattern@amount Int No The X most recent items to be copied.
File.Patterns.Pattern@recursive Bool No Whether to search recursively or not. Default: false.
File.Patterns.Pattern@isFolder Bool No If true, SLLogCollector will search for folders matching the pattern and will copy the entire content of the matching folders. Default: false.

Collectors of type Http

Collectors of type "Http" can be used to send an HTTP request to a server and store the response. You can configure them using the following XML elements and attributes:

Element/attribute Type Mandatory Description
