Unable to load JetPatch Manager Console (also update/upgrade issues)

If JetPatch Manager Console isn't coming up while trying to load it from a browser, here are a few things that might resolve the issue.

Check for McAfee (or any other Anti Virus) blocking JetPatch. This may happen after performing an upgrade.

STEP 1: Check Browser

Please make sure you are using either Firefox or Chrome.

If you receive a 404 error in the browser, then review the vmanage.log file, because something is preventing the application from starting properly.

STEP 2: Check Service Status

SSH in to your JetPatch application server. 

For each one of the below services, check that they are running in order for JetPatch to run properly.

1. nginx

systemctl status nginix.service

• • If Nginx is not loading properly, grant nginx the relevant permissions. This command could be used: 

chmod 755 /var/cache/nginx

2. tomcat

systemctl status tomcat.service

3. Postgresql (you need to add version number manually)

systemctl status Postgresql<version number>.service  

STEP 3: Proxy check

If all 3 are running and JetPatch is still not accessible, in SSH console run 

curl -kv <IP>/vmanage-server/

If the status code is 200 it is probably related to the proxy configuration. For more information on proxy setup see: JetProxy Overview

If the following actions didn’t resolve the issue and your JetPatch server is still down, please collect manager logs from the server itself , and contact JetPatch support.

STEP 4: Logs

Look at the following logs:

Apache Tomcat Logs (/usr/share/tomcat/default/logs)  
Can be useful in cases of application server failures. In cases of network problems or Java problems:

• vmange.log
• access_tomcat.<date>.log
• catalina.<date>.log
• localhost.<date>.log
• worker.log

Nginx Logs (/var/log/nginx)

Database Logs (typically it is /var/lib/pgsql/<version number>/data/).  If the service is running you can use the following command to get the exact path: 

ps -ef | grep postgres 

Memory and Space issues: Check the output of the following commands:

• free -g
• top -cH
