McAfee Web Gateway Cloud Service (WGCS) Logpuller Script - including forwarding to remote syslog/Log-Management/SIEM

McAfee Web Gateway Cloud Services (WGCS) Logpuller Script

Script to get McAfee Web Gateway Cloud Service logs from McAfee SaaS-API. Logs are downloaded to 'OutputLog.$NowUnixEpoch$.csv' and can be forwarded to a remote syslog host or SIEM when syslogEnable is set to 'True'.

Note:

When forwarding is used the downloaded CSV is transformed into a JSON stream. Configure your syslog/SIEM input correspondingly.

Timestamp is automatically adjusted with the last successful time of request. The corresponding configuration option requestTimestampFrom is updated after each run of the script.

The script is using McAfee SaaS Message API ver. 5

Python Version

Hi Schindlerd, I noticed that this script only supports Python Version 2. Will there be an upgrade to support Python Version 3?
