The pmm-managed.log is continuously printing error logs regarding evaluation_interval option

When I set the evaluation_interval option in the /srv/prometheus/prometheus.base.yml file, the pmm-managed.log is continuously printing error logs regarding evaluation_interval option.

Here is a content of the file.

# cat /srv/prometheus/prometheus.base.yml
global:
  evaluation_interval: 10s
scrape_configs:
- job_name: aaa
  honor_timestamps: false
  scrape_interval: 10s
  scrape_timeout: 9s
  scheme: https
  metrics_path: /metrics
  static_configs:
  - targets:
    - aaa:8443
  tls_config:
    insecure_skip_verify: true

Here is the logs.

I’m using the PMM Server 2.29.1 version.

How can I stop it?

Also, in that situation, the content of the /srv/prometheus/prometheus.base.yml file did not get merged into the /etc/victoriametrics-promscrape.yml file too.

Your error log says evaluation_interval is an invalid option. Can you try removing that and try again?

Thank you for your reply. But it seems that a user can set the option and it is referenced by below code block for vmalert’s evaluationInterval parameter.

percona/pmm/blob/e3e72f8d93f7ee507e34e4a3494eae28c5054211/managed/models/victoriametrics.go#L57-L82


      
          func (vmp *VictoriaMetricsParams) loadVMAlertParams() error {
          	buf, err := ioutil.ReadFile(vmp.BaseConfigPath)
          	if err != nil {
          		if !os.IsNotExist(err) {
          			return errors.Wrap(err, "cannot read baseConfigPath for VMAlertParams")
          		}
          		// fast return if users configuration doesn't exists with path
          		// /srv/prometheus/prometheus.base.yml,
          		// its maybe mounted into container by user.
          		return nil
          	}
          	var cfg config.Config
          	if err = yaml.Unmarshal(buf, &cfg); err != nil {
          		return errors.Wrap(err, "cannot unmarshal baseConfigPath for VMAlertFlags")
          	}
          	vmalertFlags := make([]string, 0, len(vmp.VMAlertFlags))
          	for _, r := range cfg.RuleFiles {
          		vmalertFlags = append(vmalertFlags, "--rule="+r)
          	}
          	if cfg.GlobalConfig.EvaluationInterval != 0 {

I just want to set the evaluationInterval for alerts. When I run the PMM 2.23.0 version with such option, it worked fine and the vmalert configured correctly with evaluationInterval parameter.

Hi. Are there any updates? Thank you for your supports in advance.
