Opmanager is attempting to contact Zoho Networks and SMTP
Introduction
A customer noted that the OpManager Probe server was attempting to send data to Manage Engine which was in violation of the Firewall rules that they had on their IP network.
Settings that may need to be changed to stop automated data collection
Settings -- Basic Settings -- System Settings -- Disable Send Usage Statistics & Send Benchmark Statistics.
This should take care of that. We get the Usage Stats and Benchmark data from customer installations and this is enabled by default. Check that these settings have been disabled in both Central & Probe
- Send Benchmark Statistics
- Send Usage Statistics
- Product promotions
- Chat support
Additional steps to take if issue continues require editing
The frequent contact to ZOHO Networks can be avoided by the below changes (to be made after stopping OpManager):
1. Got System Settings and disable "Product Promotions" (instruction above)
2. Connect to the DB via SSH and execute the below command:
- Stop OpManager "/etc/init.d/OpManagerServer stop"
- Connect to OpManager database by following steps including those in the link,
https://pitstop.manageengine.com/portal/kb/articles/connecting-to-the-opmanager-database - Run the below query:
- update ScheduleSPSettings set propval = 'false' where propname = 'SCHEDULE_UPGRADE';
- Restart OpManager. "/etc/init.d/OpManagerServer start"
To watch the OpManager services start and confirm HTTP is up use the following command
tail -F /opt/ManageEngine/OpManagerProbe/logs/wrapper.log
Sample output
[computer@Server2 ~]$ tail -F /opt/ManageEngine/OpManagerProbe/logs/wrapper.log

INFO | jvm 1 | 2018/10/05 09:41:18 | Connect to: [ https://localhost/ ]
This should stop the traffic from OpManager to ZOHO networks. We are checking other possibilities to fix this issue.
Last option is to change the SMTP settings to some bogus values, the example below is valid SMTP server in the tait network. Change the Server Name to smtp.GET_A_SERVER.null would stop emails being sent to a valid server.
