2V0-32.24 Question 152
Select 3An administrator is facing performance degradation in their vRealize Log Insight cluster. They notice that query execution is taking significantly longer than expected. Upon further inspection, they observe that one of the nodes in the cluster has an unusually high disk space utilization. What steps should the administrator take to troubleshoot and resolve this issue?
- A
Verify if the disk partition hosting the /storage/core directory is full and increase the storage if necessary.
- B
Rebalance the cluster by redistributing log data across the nodes.
- C
Restart the vRealize Log Insight cluster to clear any temporary performance issues.
- D
Check the ingestion rate settings and reduce the log ingestion rate if it exceeds recommended levels.
- E
Ensure all cluster nodes are synchronized with the same NTP server.
Show answer and explanation
Correct answers: A, B, D
Explanation
High disk space utilization on one node in a vRealize Log Insight cluster can lead to performance degradation, especially for query execution. Verifying and addressing disk space issues, rebalancing the cluster to ensure even distribution of log data, and reviewing the log ingestion rate are critical steps to resolve the problem. Restarting the cluster or NTP synchronization does not directly address the issue and may not provide a resolution.
- A. Correct.
Disk partition issues, especially on /storage/core, can lead to high disk utilization. Addressing this by freeing up space or increasing storage capacity is a critical troubleshooting step.
- B. Correct.
Rebalancing the cluster helps distribute the log data evenly across all nodes, which can alleviate performance bottlenecks caused by uneven data distribution.
- C. Incorrect.
Restarting the cluster is not a recommended troubleshooting step for this scenario as it does not address the root cause of high disk utilization or performance degradation.
- D. Correct.
Excessive log ingestion can overwhelm the cluster and lead to performance issues. Reducing the ingestion rate can help stabilize the environment.
- E. Incorrect.
While NTP synchronization is important for cluster operations, it is not directly related to addressing high disk utilization or query performance issues in this case.
