How to display the dynamic popup in a page through GTM?

This post will explain how to display the dynamic popup in a page through GTM.

The assumption is the required JQuery scripts are included as part of the page.

Define the cookie type variable:

This will help us to display the popup for every new browser session(this step is not required if the popup should displayed every time visiting the page)

• Click on Variable in left hand side menu.
• Go to user defined variables and select new.
• Select variable configuration as 1st party cookie 
• Give cookie name as popUpDisplayed and check url decode cookie option.
• Save the changes and give the name as popUpDisplayed.

java.util.concurrent.ExecutionException: hudson.util.IOException2: Failed to create a temporary file in xxxxx/figerprints/2c/73

We were receiving the following exception while executing the deployment jobs from Jenkins

java.util.concurrent.ExecutionException: hudson.util.IOException2: Failed to create a temporary file in xxxxx/figerprints/2c/73


The deployment got success after freeing some space in the server.

Pending - Waiting for next available executor/Disk space too low on /tmp - Jenkins

While we were trying to execute the job, it was displaying "Pending - Waiting for next available executor". When looking into the Jenkins node from the console, the Master node is offline and the error message displayed was "Disk space too low. Only xxxGB on /tmp" but the /tmp folder has space around 1GB.

Steps are followed to resolve the issue

• Increase the space available in /tmp folder. If not able to increase the space in /tmp folder then TemporarySpaceMonitor can be disabled or the memory threshold value of the TemporarySpaceMonitor can be reduced in $JENKINS_HOME/nodeMonitors.xml(make sure atleast minimum memory is available)

send-mail: fatal: open /etc/postfix/main.cf: No such file or directory - Linux

I was receiving the following exception "send-mail: fatal: open /etc/postfix/main.cf: No such file or directory" while trying to send the mail through cron job. But the main.cf file is available in the specified location /etc/postfix/main.cf.

I tried providing the complete permission to /etc/postfix/main.cf but this not resolved the issue.

Steps to fix the issue:

yum reinstall postfix

postfix stop
postfix start
