Not Getting anything Back When Querying Server Logs Using ArcGIS API for Python

[BHK]

I am trying to get ArcGIS Server logs using ArcGIS API for Python form this page

https://developers.arcgis.com/python/latest/guide/managing-your-gis-servers/

I am using this code

import datetime
import pandas as pd
now = datetime.datetime.now()
start_time = now - datetime.timedelta(days=10)

recent_logs = server1.logs.query(start_time = start_time)
#print a message as a sample
recent_logs['logMessages'][0]

but I am not getting anything!

but I am able to access to log setting

printing out the `recent_logs` return this

while `start_time` is this

 Can you please let me know why this is happening and how I fix this?

In your image, logMessages is an empty list, hence the index error message 

 recent_logs['logMessages'][0]

from the recent_logs dictionary with the 'logMessages' key, it is empty so trying to get the first (that is  [0] )

will return a key.

To avoid the error you would have to check its length, then if there any, get the first

msgs = recent_logs['logMessages']

msgs = recent_logs['logMessages']
if len(msgs) > 0:
    first = msgs[0]
    print("first message {}".format(first))
else:
    print("no messages")

Hey @BHK 

I know this may not be the entire answer, but something that I noticed. In your screenshot of the working logs.settings, it states that your maxHistory is 1, which means that it is only keeping the logs for 1 single day. You may try sorting the logs instead of within 10 days, to 10 hours/1 day to see if it's pulling anything correctly. I'll continue looking through to see if there's anything I can test on my side to get this replicated!

Thanks Cody! so what would be the side effects of changing the maxHistory  to 0? Is this a good idea on PROD?

Hey @BHK 

Changing maxHistory to 0 will cause all history to be indefinitely kept, this may be negligible space now, but may result in a significant amount of data being held after a long while. Depending on your log settings, if they log at the Info or Debug, you could end up with hundreds or thousands a day.

I would personally set the history time at 15, maybe even 30, to keep 15 and 30 days. That would be my recommendation, and I have mine set up to 30 in prod!
