grafana requests to akumuli

[igor-zacharov]

This is rather a question, not sure if it may be my ignorance. I'm using
akumuli 0.8.72, grafana 6.6.1, akumuli-datasource 1.3.11

In a panel that plots multiple series I get error
"Annotation Query Failed res.data.startsWith is not a function" and "bad metric name received"
if at least one of the series is not found for combination of metrics and tags in one of the queries.
Other queries may be successful for the same panel but due to the error nothing is drawn.

Can akumuli avoid returning error and just return what's available?
Or is it something I should set myself in grafana as part of the panel definition?

Thank you, Igor.

It looks like the error is in the plugin.
Could you please attach the query that causes this error and the result (if it doesn't have any sensitive information).

Eugene, here is more evidence for the problem of error "Not found". I specify two queries, 1st with data found and the 2nd with tag that doesn't match any data. But I expect grafana to make the plot for the data which is found and ignore the error for the data which is not found. I have added the files: 1) screenshot of the request from grafana which ends in error Grafana-error_req-1.PNG text file of the same Grafana-error_req-1.txt text of the Grafana query returned: Grafana-error_resp-1.txt screenshot of the grafana panel that shows how the tags are specified: Grafana-error_req-2.PNG here the cpu.temp is the one which is found, while net.if_temp with tag net_if=eth_log is not found 2) screenshot of the request when I remove the tag that leads to the data not found: Grafana-error_resp-2.PNG 3) same request when I allow for series with NULL or ZERO data in them: Grafana-error_resp-3.PNG This shows that data exists, but just not matching the tag specified. If there is only one metric to plot and the tag does not match the data, then the error returned "data not found" is appropriate. Thank you, Igor.
