Zeebe backpressure request limit not changing

[ankit_joinwal]

We have set the following environment variables in our helm

env:
  - name: ZEEBE_BROKER_BACKPRESSURE_ENABLED
    value: "true"
  - name: ZEEBE_BROKER_BACKPRESSURE_ALGORITHM
    value: "fixed"
  - name: ZEEBE_BROKER_BACKPRESSURE_FIXEDLIMIT_LIMIT
    value: "100"

However, we are not noticing any change to the metric zeebe_backpressure_requests_limit . Seems it is always 20 which I believe is the default value.

Are we missing anything?

Hi @ankit_joinwal,

It looks like the variable name is incorrect. Can you please try with the following variable name:

env:
  ...
  - name: ZEEBE_BROKER_BACKPRESSURE_FIXED_LIMIT
    value: "100"

Just for reference, please remove LIMIT from _FIXEDLIMIT_.

Does it solve the issue for you?

Best,
Roman

Can you also please point me to the documentation where the Env variable name is mentioned? just for reference.

I will try the suggestion and let you know.

Sure.

• General documentation about environment variables: Environment variables | Camunda Platform 8
• All environment variables in the file config templates: Configuration | Camunda Platform 8

Eventually, you can find the correct variable name in the config file: zeebe/broker.yaml.template at 77114d686411407673e03c913cd584540eb79ba0 · camunda/zeebe · GitHub

Let me know if that helps.

Best,
Roman
