at customer we use Remote Windows host extension 1.3.12 running on seperate windows AG (latest version 1.299.33) monitoring 29 endpoints with just several feature sets (default, network intfcs, pagerfile metrics). So consumption of ddu is relatively low (3250/24h). Number of post requests from that AG (metric dsfm:active_gate.rest.request_count in self monitoring env) shows 336k requests/24h.
Other 2 AGs running with much higher volume extensions (f.e. MSSQL Server extension with 68k DDU/24h) produces much lower number of post requests (85k, 66k).
Thanks for your info, but in this issue it’s irrelevant. AG is already at High limits as all other AGs running extensions at this customer. I described issue in specific wmi data source based extension (Remote Windows Host Monitoring).
3.99M lines with 336K requests suggests more than 10 lines per request. This might be a good indicator, because sending several lines in the same request is better than sending a line per request.
Since it consumes 3250 DDUs, this would mean that only 3.25M lines were “licensed”. This maybe related to a metric data point being sent more than once for the same minute (I have seen this in the past with WMI) or eventually lines with descriptions and not data.
For point #2 I would suggest scanning the metrics to see if someone has a count != 1 for each of the dimensions.
I suppose, that it’s multiple sending of same metrics all the time. It’s dynatrace created extension, so probably someone responsible should check this post. I had checked counts and it’s 1 in all checked metrics with host/dimension split.
I wouldn’t say that it’s performing badly, the WMI data source is just more chatty than other data sources. If this is a problem, please open a support ticket.
