The full restart this time did clear out the high values that were left in the monitoring. But this is reproducible enough

that a ticket should still be opened.

I would like to request that a ticket be opened to track this bug

OK now the queues are completely empty and the factory has only one glidein running.. yet

the monitoring still shows thousands of cores running.

This is the last time we had any idle jobs in the queue at all, at 08:18 this morning

Whenever there are idle jobs in the queue, the GlideinMonitorTotalClientclassads come back with the same
wrong numbers they had before. When there are not idle jobs, within 30 minutes the glideclient and glidefactoryclient
classads go away.

I have once again stopped the decision engines and the factory, waited for all classads to go away out of
condor_status -any and then restarted.

We will see what happens when jobs next hit the queue.

Subject: Re: fermifactory02 monitoring is wrong somehow

There appear to be two different problems going on:

1) t he glidefactory classads are left with unrealistically high values of variables relating to GlideinMonitorTotalClient*

(see ckassad CMSHTPC_T3_US_NERSC_Cori_KNL@gfactory_instance_fermifactory02@gfactory_service_fermifactory02)

GlideinMonitorTotalClientMonitorCoresIdle = 8
GlideinMonitorTotalClientMonitorCoresRunning = 8722
GlideinMonitorTotalClientMonitorCoresTotal = 8772
GlideinMonitorTotalClientMonitorGlideIdle = 1
GlideinMonitorTotalClientMonitorGlideRunning = 871
GlideinMonitorTotalClientMonitorGlideTotal = 1000
GlideinMonitorTotalClientMonitorInfoAge = 13

The GlideinMonitorTotal variables in that same classad are correct

GlideinMonitorTotalStatusRunning = 28
GlideinMonitorTotalStatusRunningCores = 1904

There are only 28 glideins running, not 1000. There were at one point 8722 cores running but not anymore, the 1904

value is right.

I believe that something goes wrong with the TotalClientMonitor values above if

there are not glideclient classads being sent all the time. The decision engine only sends

those ads if there are idle jobs in the queue that match the group in question. About half the time at the moment

there is nothing idle.

2) The frontend-like code in the decision engine refuses to request new glideins on the basis that a number

of jobs in the group are already running. earlier in this email thread that number was accurately reported to be 8545,

now it is reported to be 250 or so. Those numbers are accurate.

The problem is that the count of running jobs includes the number of jobs that are running on any entry at all.

of those 250 jobs, 50 of them or so are running at other sites in the OSG, 196 are running at NERSC, none

at all are running at SDSC. Also as previously mentioned I have 3 groups defined in the DE for which the jobs

almost completely overlap.

If I'm right, then once the amount of running jobs gets down to near zero (later tonight at 11 PM when the last NERSC glideins exit) then SDSC will finally get some glideins submitted again. We will see.

I restarted the factory and both decision engines that talk to it. Left it down long enough

so that all glideclient and glidefactoryclient classads drained out. On cold restart

we came to exactly the same position we were at before:

So here we are again--17072 jobs pending and only 2 glideins sent out.

Factory limit is 144.

This is a very weird corner case.. it may be because the groups overlap to a large extent.

i.e. the jobs that match NERSC, SDSC, and Bridges are all in 3 different groups but the

groups overlap significantly

Perhaps killing and restarting the factory would help?

Some of the monitoring appears to be confused.. in particular it seems that the

ClientMonitor fields are quite confused from the glideclient/glidefactoryclient/glidefactory classads

GlideinMonitorTotalClientMonitorCoresIdle = 408
GlideinMonitorTotalClientMonitorCoresRunning = 325
GlideinMonitorTotalClientMonitorCoresTotal = 748

The above numbers are for entry CMSHTPC_T3_US_NERSC_Cori_KNL and are an underestimate of what is actualy running.. there

are 117 glideins active on that entry and they are all from the same glideclient group cms_nersc_passthrough on decision engine cmsde01

Look if you will at fermifactory02

condor_status -any -constraint 'MyType=="glidefactory"&&EntryName=="CMSHTPC_T3_US_NERSC_Cori_KNL"'

All are underestimating the total number of glideins running.

The standing requests are the following from cmsde01 (in 3 different groups, cms_nersc_passthrough for the 1st 2, cms_xsede_passthrough,
and cms_sdsc passthrough)

In the last hour since I've been describing this problem the requesst for Cori_KNL went up significantly (from 3 idle 16 running to 19 idle 26 running in last hour) but I would expect that
the request for SDSC should be much higher too and it is only requesting one idle glidein and 2 running.
