Reading sas viya log

[jbond007]

Hi SAS Community, 

I am new to viya and need your help. There is a frequent disconnection on our SASVA and would like to understand how to read the log. there are so many written on the log would like to understand the numbers..

Are the below numbers represent a certain process/pid? 
[00000007]

5776

17778

I believe these numbers represent the thread, client PID, and session ID, respectively. You can look at the logconfig file to see how the message lines are being formed:

$ grep Conv /opt/sas/viya/config/etc/cas/default/logconfig.xml
<param name="ConversionPattern" value="%d %-5p [%t] %X{Cas.ClientPid|MAIN} %X{Cas.ClientUser|NoUser} %X{Cas.SessionIndex|MAIN} [%F:%L] - %m"/>
<param name="ConversionPattern" value="%d %-5p %X{Cas.ClientPid|MAIN} %X{Cas.ClientUser|NoUser} %X{Cas.SessionIndex|MAIN} - %m"/>
<param name="ConversionPattern" value="%-5p [%t] %X{Cas.ClientPid|MAIN} %X{Cas.ClientUser|NoUser} %X{Cas.SessionIndex|MAIN} [%F:%L] - %m"/>
