OpenVPN

Background

The OpenVPN Servers logs analysis App automatically Collect - Read - Parse - Analyzes - Reports all machine generated log data of the server and presents a comprehensive set of graphs and reports to analyze machine generated data. Use a predefined set of dashboards and gadgets to  visualize and address the system software, code written, and infrastructure during development, testing, and production. This logs analysis App helps measure, troubleshoot, and optimize your servers integrity, stability and quality with the several visualization and investigation dashboards.

Steps:

1. The OpenVPN App is running on messages/syslog, auth/secure, mail, kern and cron standard logs.
   When adding/editing the logs to XpoLog it is mandatory to apply the correct log type(s) to each of the logs:
   1. openvpn - all logs that the application will analyze must have openvpn as a log type.
      
   2. linux - all logs that the application will analyze must have linux as a log type.
   3. messages/syslog - only the messages/syslog logs must also be configured to have messages/syslog as a log type.
   4. auth/secure - only the auth/secure logs must also be configured to have auth/secure as a log type.
   5. cron - only the cron log must also be configured to have cron as a log type.
   6. mail - only the mail log must also be configured to have mail as a log type.
   7. kernel  - only the kern log must also be configured to have kernel as a log type.
   
   
2. Once the required information is set, on each log click next and edit the log pattern, this step is crucial to the accuracy and deployment of the OpenVPN App. Use the following patterns for each of the logs:
   
   1. Linux messages/syslog log:
      {date:Date,MMM dd HH:mm:ss} {text:source,ftype=source} {text:process name,ftype=process;,}{block,start,emptiness=true}[{text:pid,ftype=pid}]{block,end,emptiness=true}: {text:Message,ftype=message;,}{regexp:User,ftype=user;refName=message,[passed|failed] for (.*) from}
   2. Linux auth/secure log:
      {date:Date,MMM dd HH:mm:ss} {text:SourceIP,ftype=source} {text:Process,ftype=process}{block,start,emptiness=true}[{text:pid,ftype=pid}]{block,end,emptiness=true}: {text:Message,ftype=message}
   3. Linux cron log:
      {date:Date,MMM dd HH:mm:ss} {text:Server,ftype=server} {text:Process,ftype=process}{block,start,emptiness=true}[{text:pid,ftype=pid}]{block,end,emptiness=true}: {text:Message,ftype=message}
   4. Linux mail log:
      {date:Date,MMM dd HH:mm:ss} {text:source} {text:process name,ftype=process;,}{block,start,emptiness=true}[{number:process id}]{block,end,emptiness=true}: {regexp:session,refName=Message;ftype=session,^(\w+):}{regexp:From,refName=Message;ftype=from,\s+from=([^,]+)}{regexp:To,refName=Message;ftype=to,\s+to=([^,]+)}{text:Message,ftype=message;,}
   5. Linux kernel log:
      {date:Date,MMM dd HH:mm:ss} {text:source,ftype=source} {text:process name,ftype=process;,}: [{text:time-taken,ftype=time-taken;,}] {text:Message,ftype=message}
