Starting from QueueMetrics 26.01, queuemetrics-tomcat requires an updated version of RPM that CentOS 7 does not provide, because CentOS 7 reached its official End of Life (EOL) on June 30, 2024.

For that reason, we strongly recommend migrating to a different version of operating system to ensure system security.

For this reason, if you want to install or update QueueMetrics or Wombat Dialer on CentOS 7, you must follow a specific procedure.

This guide shows a workaround by using a version of queuemetrics-tomcat that is still compatible with CentOS 7.

Note: This applies to CentOS 7 and all CentOS 7/RedHat 7 based distributions, including Sangoma 7 (FreePBX 14, 15, and 16).

Fresh Installation of QueueMetrics

To perform a fresh installation of QueueMetrics, run the following commands:

wget https://yum.loway.ch/loway.repo -O /etc/yum.repos.d/loway.repo
yum install https://downloads.loway.ch/software/queuemetrics-tomcat/queuemetrics-tomcat-9.0.113-1.noarch.rpm
yum install queuemetrics

Updating QueueMetrics

To perform an update of QueueMetrics, run the following commands:

yum update queuemetrics

Running a full system update (yum update) on a machine with QueueMetrics installed will fail, because it pulls newer queuemetrics-tomcat package that is no longer compatible with CentOS 7.
