What other Windows capabilities should we consider?

[peterbom]

From #168, we have now already:

• Added Windows support for all collectors that aren't Linux-specific, including arbitrary file-system logs
• Enabled OSM/SMI collectors
• Included output from collect-windows-logs.ps1 (for supported clusters)

There will probably be diminishing returns for the work involved in further Windows capabilities, and so these may not be addressed in the near term but should be noted for future consideration. These include:

• Kubelet collector (which analyses the command line arguments used to invoke the kubelet). This was originally noted as probably being unachievable in Windows, but with host-process containers is likely now achievable (or even trivial).
• The Windows equivalent of the DnsCollector which reads resolv.conf (in both the container and host). However, I haven't fully explored the collect-windows-logs output, and it's possible this contains enough DNS information already.
• A Windows equivalent of the iptables output. Again, something like this might already be in the collect-windows-logs output.

Any more ideas can be added here.

@peterbom One thing we noticed on a large cluster, the data can be overwhelming on what is collected.

If we wanted to just collect windows logs or networkoutbond logs, etc. Is it possible to customize the yaml and only collect data from the provided collector?

[peterbom]

@sumicalbin - that's not currently possible. The philosophy of Periscope is to collect as much information as possible, as the tool itself can't predict which information will be relevant for troubleshooting.

Also, the script we run is not maintained by us, and from chatting with @AbelHu I don't believe there are any plans for selectively specifying which logs to collect. One alternative Abel suggested was the loggenerator.ps1 script. This doesn't call collectlogs.ps1 and I haven't yet had a chance to understand all the differences, or when you might want to use each. But if it's helpful, one possible enhancement to Periscope might be to allow users to specify which script gets run.

I see, thanks for the explanation. It would definitely be a great enhancement to see down the line.
