Query server logs using python script not returning results

If I submit a request with just the 'services' parameter for the filter, I get no results:

If I include all of the default paramters, I do:

Since you want the results from specific servers, what if you try to include the default parameters for the filter:

{"codes":[],
"processIds":[],
"server": "*",
"services": ["SampleWorldCities.MapServer"],
"machines": "*"}

But pass in the server name for the "server" value through the for loop. I'm not sure why errors unrelated to SampleWorldCities are returning, but that's a separate problem.

@JonathanQuinn any findings regarding the below. We are also getting unrelated results when passed "services" parameter with a service name. We are using ArcGIS Server 10.8.1.

I am having the same issue, so I modified my Params to this:

params = urllib.urlencode({
    'startTime':starttime,
    'endTime':endtime,
    'server':serverName,
    'level': 'WARNING',
    'filter': logFilter,
    'token': token,
    'pageSize': 100,
    'f': 'json'})

but I am still getting a output of : {u'logMessages': [], u'endTime': 0, u'hasMore': False, u'startTime': 0} Not sure what I am doing wrong.

That worked! Thanks!
