fastnetmon problem

[Ghazaleh Farjood]

hi

I am currently using version 1.2.6  fastnetmon community and I have a problem and need help :

Traffic logs were sent from fastnetmon to syslog server (SIEM) but now all types of logs are sent except traffic logs - The service has been restarted and the whole VM has been rebooted, but there is no more traffic log on the path /var/log/fastnetmon.log  - 

It is not saved, therefore it is not sent to Splunk(SIEM) and Syslog

the traffic in fastnetmon_client is so good and  completely visible only in /var/log/fastnetmon.log, nothing is displayed from the traffic log-  config file has not changed.

sample of traffic log : 

[ERROR] Traffic was calculated in: 1 sec 10193 microseconds

ALERT. Toolkit working incorrectly. We should calculate speed counters in <1 second

Hello!

That's very likely caused by the huge number of monitored networks.

Community edition can handle around 100k IPs (total size of hosts in your networks) on top grade CPUs with very high frequency. 

If you have more then Advanced edition may be better choice as it can maintain up to million of active hosts easily: https://fastnetmon.com/docs-fnm-advanced/flexible-counters-for-traffic-calculation/

Thank you!
