Issue/Introduction

This article describes how to troubleshoot cloud platform monitoring data that is not displayed. It applies to the initial diagnosis and resolution of similar issues in ZStack Cloud.

Environment

• Product: ZCF
• Component: Cloud
• Version: 3.x-5.5.30

Resolution

Try the following methods:

• Log in to the host and run cat /etc/sysconfig/iptables to check whether ports 7069, 9100, and 9103 are open. If they are not open, try reconnecting the host.
• Open $HOST_IP:9103 in a browser and check the specific monitoring data that is not displayed. For example, search for a VM instance UUID to view its monitoring data. If the monitoring data is not displayed, log in to the host, run pkill collectd to stop the collectd service, and then try reconnecting the host.
• Check whether the owner of the management node path /var/lib/zstack/prometheus/data2 is zstack. If the owner is not zstack, run pkill prometheus to stop the prometheus service, and wait 30 seconds for the management node to start it automatically.
• If monitoring data is still not displayed after the preceding operations, try restarting the host or deleting and re-adding it.
