mc support profile

Description

The mc support profile command runs a system profile for your deployment. The results of the profile can provide insight into the MinIO server process running on a given node.

The resulting report is intended for use by MinIO Engineering. You can upload the report to |subnet|. Independent or third-party use of these profiles for diagnostics and remediation is done at your own risk.

Examples

Fetch CPU Profiling

This command retrieves the CPU profile on a MinIO deployment with the alias minio1. The profile runs for the default of 10 seconds.

mc support profile --type cpu minio1/

Fetch CPU, Memory, and Block Profiling Concurrently

This command fetches the profile of the CPU, memory, and block usage on the alias minio2. The profile runs for the default of 10 seconds.

mc support profile --type cpu,mem,block minio2/

Fetch CPU, Memory, and Block Profiling Concurrently for 10 Minutes

This command fetches the profile of the CPU, memory, and block on the alias minio3. The profile runs for 10 minutes (600 seconds).

mc support profile --type cpu,mem,block --duration 600 minio3/

Syntax

The mc support profile command has the following syntax:

mc [GLOBALFLAGS] support profile       \
                         COMMAND       \
                         [--type]      \
                         [--airgap]    \
                         [--duration]  \
                         ALIAS

Parameters

--duration

Run profiling for the specified duration in seconds.

Use --type <value> where <value> is the number of seconds for the profile to run.

If not specified, the command collects data for 10 seconds.

--type

Specify the profile(s) to gather data for.

Use --type <value> where <value> is one or more comma-separated types of data to collect.

Valid types are:

cpu
cpuio
mem
block
mutex
trace
threads
goroutines

If not specified, the command collects data for CPU, memory, block, mutex, threads, and goroutines.

Important

Do not use the cpuio or trace data types unless directed to by MinIO Support. These profiles require significant resources and may degrade cluster performance if used without guidance.

--airgap

Use in environments without network access to SUBNET (for example, airgapped, firewalled, or similar configuration).

If the deployment is airgapped, but the local device where you are using the minio client <minio-client> has network access, you do not need to use the --airgap flag.

ALIAS

The alias <alias> of the MinIO deployment.
