test 1 - single resource, update schedule, agent online
1) go to some resource in inventory whose agent is up 2) navigate to monitor > configuration subtab 3) change some collection interval to something odd like 42s 4) go to that agent prompt and execute "inventory -x -e inv.dat" 5) then in a sep terminal execute "cat inv.dat | grep 42000 -c" and make sure the count is precisely 1 test 2 - single resource, disable schedule, agent online 1) go to some resource in inventory whose agent is up 2) navigate to monitor > configuration subtab 3) disable the collection interval that you previously marked with 42s 4) go to that agent prompt and execute "inventory -x -e inv.dat" 5) then in a sep terminal execute "cat inv.dat | grep 42000 -B 1" to make sure this schedule has been disabled agent-side test 3 - single resource, update schedule, agent offline
1) repeat steps 1-3 from test 1...but change the time to, say, 31 seconds 2) turn the agent back on and wait 30-60 seconds for the first inventory report to be sent (you can confirm when this happens if you tail the server log) 3) repeat steps 4 & 5 from test 1 test 4 - single resource, disable schedule, agent offline 1) repeat steps 1-3 from test 2...but disable the one you just set to 31 seconds 2) turn the agent back on and wait 30-60 seconds for the first inventory report to be sent (you can confirm when this happens if you tail the server log) 3) repeat steps 4 & 5 from test 2 test 5 - multi-resource, update schedule, agent online
1) go to admin > monitoring defaults > choose some resource type (and make sure you count the number of resources of that type in your inventory, we'll call this value X) 2) change some collection interval for a single schedule to something odd like 53s 3) go to that agent prompt and execute "inventory -x -e inv.dat" 4) then in a sep terminal execute "cat inv.dat | grep 53000 -c" and make sure the count is precisely X test 6 - multi-resource, disable schedule, agent online 1) go to admin > monitoring defaults > choose some resource type (and make sure you count the number of resources of that type in your inventory, we'll call this value X) 2) disable the collection interval that you previously marked with 53s 3) go to that agent prompt and execute "inventory -x -e inv.dat" 4) then in a sep terminal execute "cat inv.dat | grep 53000 -B 1" and make sure that all X entries are disabled now test 7 - multi-resource, update schedule, agent offline
1) repeat steps 1 & 2 from test 5, but change the time to, say, 67 seconds 2) turn the agent back on and wait 30-60 seconds for the first inventory report to be sent (you can confirm when this happens if you tail the server log) 3) repeat steps 3 & 4 from test 5 test 8 - multi-resource, disable schedule, agent offline 1) repeat steps 1 & 2 from test 6, but disable the one you just set to 67 seconds 2) turn the agent back on and wait 30-60 seconds for the first inventory report to be sent (you can confirm when this happens if you tail the server log) 3) repeat steps 3 & 4 from test 6 rev1375 - scale back logging on the sever-side for measurement schedule and metric template updates;

Improvement
Accepted
Critical
asynchronous updating of metric tempates / schedules
on the crazy off-chance that the AgentClient is available but sending the report fails, catch Throwable to make sure the caller's request will continue to completion;
update mtime's of resources whose MeasurementSchedules are being changed (directly on the resource, or indirectly through the metric template);
while i was at it, improve the performance of the end-to-end flow for metric tempalte updates by batch all ResourceMeasurementSchedulesRequest's for a single agent into a single remote method call and, more importantly, single check against the availability of the corresponding AgentClient;
