Creating Sumologic native SLO's and monitors from OpenSLO yaml configs

slogen supports native sumologic SLO creation from spec version v1 of OpenSLO.

Samples can be found in the samples/sumologic/v1 directory.

They can be tried out as below from the root of the repo.

go run main.go samples/sumologic/v1 --clean --onlyNative=true --sloFolder=slogen-v1 --sloMonitorFolder=slogen-v

OpenSLO SLI to Sumologic SLI fields mapping

  • the name value specified in metadata:name field of the OpenSLO spec is used as the SLO name
  • Budgeting method Occurrences maps to Request based SLO's while Timeslices maps to Window based SLO's
  • use sumologic-logs as metricSource:type for logs based Indicators, while sumologic-metrics for metrics based Indicators

Using Alerting Policies to create SLO monitors

For now slogen doesn't support inline alerting conditional in SLO config yaml. Alerting policies need to specified separately as showed in the samples and then can be referred by name the SLO config.

To specify the critical and warning threshold use the same condition name while changing the severity level as done in the samples.

alert notification targets

Notification targets can be specified in the OpenSLO format while using the annotations field for specifying the extra parameters required. These targets can then be referred in the alert policy config to generate the monitors.

Examples below

email based notification target
apiVersion: openslo/v1
kind: AlertNotificationTarget
spec:
  description: Notifies by a mail message to the on-call devops mailing group
  target: email
metadata:
  name: OnCallDevopsMailNotification
  annotations:
    recipients: "agaurav@sumologic.com"
    subject: "Monitor Alert: {{TriggerType}} on {{Name}}"
    message_body: "Triggered {{TriggerType}} Alert on {{Name}}: {{QueryURL}}"
    time_zone: "PST"
    run_for_triggers: "Critical,ResolvedCritical"
connection based notification target
apiVersion: openslo/v1
kind: AlertNotificationTarget
spec:
  description: Notifies by a mail message to the on-call devops mailing group
  target: connection
metadata:
  name: OnCallDevopsSlackNotification
  annotations:
    connection_type : "Webhook"
    connection_id: "0000000000000431"
    run_for_triggers: "Critical,ResolvedCritical"

Specifying SLO and monitor folders

The annotation field sumologic/slo-folder-id can be used to specify the id of the folder in which the SLO should be created. Similarly, the annotation field sumologic/slo-monitor-folder-id can be used to specify the id of the folder in which the SLO monitor should be created.

e.g.

apiVersion: openslo/v1
kind: SLO
metadata:
  name: drift_gen_Calendar
  displayName: DriftGen SLO Calendar
  annotations:
    sumologic/signal-type: Latency
    sumologic/tf-resource-name: slo-driftgen-latency-calendar
    sumologic/slo-folder-id: 0000000000000ABC
    sumologic/monitor-folder-id: 0000000000026ABC
spec:
  description: test slo created from slogen
  service: tsat
  indicator:
    metadata:
...

Renaming SLO name while retaining old SLO's in sumo

The annotation field sumologic/tf-resource-name can be used to pin the terraform resource name, thus allowing the SLO name to be changed without destroying the old SLO in sumo. This is required as otherwise the terraform resource name is derived from SLO name and its service.
