Introduction
Dashboards in VMware vRealize Log Insight provide a visual representation of log data, allowing users to monitor and analyze the state of their infrastructure in real time. Dashboards are composed of widgets that display data from log queries, making it easier to identify trends, spot anomalies, and gain insights.
While working on the Log Insight Setup, you might come across an issue where you are not able to load the Dashboard items and they are just stuck in loading.
To investigate this, you might have to reconsider the decisions that you took while configuring your Log Insight Infrastructure.
Now as per the screenshot below, we can see that the Log Insight VM is configured with 8 CPU and 16 GB RAM.
As per the Article: https://docs.vmware.com/en/VMware-Validated-Design/4.1/com.vmware.vvd.mseg-design.doc/GUID-7E2833A8-047C-4C36-A877-CB0982AB5266.html is Medium.
So as per the above article, the Ingestion rate for a Medium Deployment cannot be above 5000 Events/Seconds.
Now, let’s understand how our Log Insight is holding up.
If you will go to the Admin Page of Log Insight please check if you have any Active Queries showing as queued for a long time.
In Order to Understand the root of this issue. Let’s check the Statistics tab under the System Monitor page:
For our Environment, the Ingestion rate of logs is beyond 5000 Due to this we have queries getting queued, and due to this reason we are not able to see the Dashboard.
Recommendation:
Increase the RAM and Memory of all of the Log Insight Nodes so that they are capable of handling these Ingestion rate values.
As per the Article: https://docs.vmware.com/en/VMware-Validated-Design/4.1/com.vmware.vvd.mseg-design.doc/GUID-7E2833A8-047C-4C36-A877-CB0982AB5266.html
This can be a Large Deployment i.e. 32 GB RAM and 16 VCPUs.
