Issue/Introduction

Title: Alarm for Edge Datapath mempool usage high
Event ID: edge_health.edge_datapath_mempool_high

Alarm Description

  • Purpose: Tracks usage percentage of various mempools.
  • Impact: Functionality corresponding to the specific mempool will be impacted.

Environment

VMware NSX-T Data Center

Resolution

Steps to Resolve

For 3.0.0 and higher

Recommended action: Get the mempool usage using 'get dataplane memory stats' CLI.

  1. In case of high usage in malloc heap mempool, grep 'malloc_heap' in the syslog file to get the pattern for an increase in usage. If the free space is fairly consistent across all the logs, it just means high usage of malloc_heap and there won't be any functional or traffic disruption.
  2. Firewall-related mempool usage high means capacity is low. Move the Edge to a larger form factor or increase the number of Edge nodes in the Edge cluster.
  3. Increase Edge form factor if an alarm is raised after upgrading to a new configuration.

Maintenance window required for remediation? Yes
