MS Log Analytics Add-On checkpointer error

[plaxosi]

After defining a new input (named AzureMetrics) I see the following error every 60 seconds (i.e. the configured interval):

DEBUG pid=XXXX tid=MainThread file=connectionpool.py:_make_request:387 | "GET /servicesNS/nobody/TA-ms-loganalytics/storage/collections/data/TA_ms_loganalytics_checkpointer/AzureMetrics HTTP/1.1" 404 140

After the 404 error there are no other DEBUG messages for the pid.

A previously configured input works fine, i.e. gets a 200 response code when fetching the last checkpoint and then fetches the LogAnalytics data (and produces more DEBUG messages for the same pid).

Looking in the KVStore I see that there is no entry for _key=AzureMetrics, hence the 404, whereas there is an entry for the input that works.

It seems like an initial checkpoint entry should be written to the KV Store. I have tried changing the configured "start date" for the input, but that does not help. Is there something else I need to do here?

Unfortunately I wasn't able to solve the multiple inputs/checkpoints issue in this app due to the way the add on builder works.

You can work around it by installing the app on multiple HFs and configuring one input per forwarder.
