I currently have a task that monitors for the number of docker containers running dropping. For this type of alarm, I really don't need it to recover or even have state levels. I just want to know if it occurred. With the tick script below I get the alert indicating that the number has dropped by one, but I don't want the state to go back to OK, i.e. just want one alert.
Is there anyway to accomplish this with the alert node? Thanks TICK SCRIPT START //This task will alert on changes in the number of running containers, //if the number drops it could indicate that the container exited. var data = stream |from() .database(database) .retentionPolicy(retention_policy) .measurement('docker') .groupBy('host') |where(lambda: "deployment" == deployment) |eval(lambda: "n_containers") .as('_n_containers') .keep() .quiet() |window() .period(1m) .every(1m) //|log() //Uncomment to debug var min_value = data |min('_n_containers') .as('value') var max_value = data |max('_n_containers') .as('value') //Compute the delta between min and max, by joining two window outputs //If negative change we lost a container min_value |join(max_value) .as('min_running', 'max_running') |eval(lambda: "min_running.value" - "max_running.value") .as('change_delta') |alert() .info(lambda: "change_delta" < 0) .infoReset(lambda: "change_delta" >= 0) .message('\'{{.TaskName}}\' --> \'{{ .Level }}\' Host \'{{ index .Tags "host" }}\' Number of running containers has changed by \'{{ index .Fields "change_delta" }}\'') .slack() .channel(slack_channel) -- Remember to include the version number! --- You received this message because you are subscribed to the Google Groups "InfluxData" group.
