Resource profiles

Chronosphere Telemetry Pipeline offers templates called resource profiles that let you strike a balance between pipelines’ performance and reliability. These templates include different combinations of settings optimized for various scenarios. You can also edit resource profiles to customize behavior related to buffering and resource consumption.

Resource profiles are applied to pipelines when you deploy them.

Profile specifications

Telemetry Pipeline includes these profile specifications:

Resource profiles only support storage configurations. Memory and CPU limits can be set in the profile, but by default no limits are set.

Profile properties

Use the following settings to modify your profile:

Pipeline CLI commands

Use the following Pipeline CLI commands to interact with resource profiles.

Specify the resource profile for a new pipeline

Set the resource profile for a new pipeline by using the following command:

calyptia create pipeline --core-instance INSTANCE --name PIPELINE --resource-profile PROFILE

Replace the following:

• INSTANCE: The name of your Core Instance.
• PIPELINE: A name for your new pipeline.
• PROFILE: The name of the resource profile to use.

Update the resource profile for an existing pipeline

Update the resource profile for an existing pipeline by using the following command:

calyptia update pipeline --name PIPELINE --resource-profile PROFILE

Replace the following:

• PIPELINE: The name or unique ID of your pipeline.
• PROFILE: The name of the resource profile to use.

Define a new resource profile

Use the following command to define your own resource profiles in Telemetry Pipeline:

calyptia create resource_profile --core-instance INSTANCE --name PROFILE --spec FILE_NAME

Replace the following:

• INSTANCE: The name of your Core Instance.
• PROFILE: A name for your new resource profile.
• FILE_NAME: The JSON configuration file that defines your resource profile.

Resource profile JSON files follow this schema:

This is an example of a resource profile definition:

{
 "resources": {
  "storage": {
   "syncFull": false,
   "backlogMemLimit": "5M",
   "volumeSize": "250Mi",
   "maxChunksUp": 128,
   "maxChunksPause": false
  },
  "cpu": {
   "limit": "0",
   "request": "0"
  },
  "memory": {
   "limit": "0",
   "request": "0"
  }
 }
}

A 0 value is defined as unlimited.

List available resource profiles

Use the following command to list the resource profiles defined within a Core Instance:

calyptia get resource_profiles --core-instance CORE_INSTANCE

Replace CORE_INSTANCE with the name of the Core Instance.

Get details about a resource profile

Use the following command to get details about a specific resource profile:

calyptia get resource_profile PROFILE

Replace PROFILE with the name of that resource profile.

Delete a resource profile

Use the following command to delete a specific resource profile:

calyptia delete resource_profile PROFILE

Replace PROFILE with the name of that resource profile.
