Panic on Windows during record #902

Closed andycarlsonuk closed 7 years ago

andycarlsonuk commented 8 years ago

I suspect that Windows is not well supported or widely used but the binary is available so I gave it a try. Some things worked for me but not enough to create usable alerts. I've tried 0.13.0, 0.13.1 and 1.0.0 with similar results. The same things work fine on a Linux VM.

Here is one example of a panic...

E:\kapacitor-1.0.0-1>kapacitor show amdocs_cpu ID: amdocs_cpu Error: Template: Type: batch Status: disabled Executing: false Created: 14 Sep 16 15:57 BST Modified: 14 Sep 16 16:13 BST LastEnabled: 01 Jan 01 00:00 UTC Databases Retention Policies: ["amdocs"."default"] TICKscript: batch |query(''' SELECT mean(totalpct) FROM "amdocs"."default"."sar_cpu" ''') .period(1h) .every(1h) .groupBy(time(20m), 'host') |alert() .crit(lambda: "mean" > 25) .log('e:\temp\alerts.log')

DOT: digraph amdocs_cpu { query1 -> alert2; }

E:\kapacitor-1.0.0-1>kapacitor record batch -task amdocs_cpu -past 24h Post http://localhost:9092/kapacitor/v1/recordings/batch: read tcp [::1]:63565->[::1]:9092: wsarecv: An existing connection was forcibly closed by the remote host.

The backslashes in the above text shown by GitHub are actually double backslashes in my files. I guess I should have posted four backslashes. Sorry for any confusion.
