The average percentage CPU used by all instances of your microservice

The number of container kills to alert on

 
.withContainerKillThreshold(5) # alert if 5 microservice instances are killed with an out-of-memory exception in a 15-minute
 window 

The number of logs at ERROR level that this alert will trigger on

The number of exceptions thrown that this alert will trigger on

The %age of requests that must be 5xx to trigger the alarm

The minimum count of 5xxs that must be present for the percentThreshold check to kick in. Optional. If you want to create a 5xxPercentThreshold alert but only if you have a given count of 5xxs, this is the method to use. You want to use this parameter if, for example, you don't want to alert on just a one-off 5xx in the middle of the night Defaults to 0, which would mean the parameter has no effect.

How severe the alert is

Configured threshold object

The number of all http responses with a 5xx status code to alert on

Whether to raise the alert as critical or warning

Object representing the response time in milliseconds above which alerts will be raised at given severities for a given time period

Object with fields percentThreshold, crossover, absoluteThreshold, hysteresis, excludeSpikes, errorFilter, target, severity

Object with fields percentThreshold, crossover, absoluteThreshold, hysteresis, excludeSpikes, errorFilter, target, severity

Object with fields percentThreshold, crossover, absoluteThreshold, hysteresis, excludeSpikes, errorFilter, severity

Object with fields httpStatus, percentage, severity and httpMethod

 
.withHttpStatusPercentThreshold(HttpStatusPercentThreshold(HTTP_STATUS_404, 25.0)) # alert when 25% of all requests return status
 code 404 in a 15-minute window .withHttpStatusPercentThreshold(HttpStatusPercentThreshold(HTTP_STATUS_500, 25.0)) # alert when 25% of all
 requests return status code 500 in a 15-minute window .withHttpStatusPercentThreshold(HttpStatusPercentThreshold(HTTP_STATUS_504, 25.0,
 AlertSeverity.Warning, httpMethod.Post)) # raise a warning alert when 25% of all Post requests return status code 500 in a 15-minute window 

Object with fields httpStatus, count, severity and httpMethod

Object with fields warning, critical and maxMinutesBelowThreshold

List of names of your pagerduty integrations. These integrations must already exist in PagerDuty; alert-config will not create then for you.

The substring to search for in the log message

The threshold above which an alert will be raised

Flips the logic so that an alert is raised if less than the threshold amount is detected

The severity to set for this check in PagerDuty

 
.withLogMessageThreshold("Custom logs", 5) // occurrences of a specific log message in a 15-minute window
 .withLogMessageThreshold("heartbeat", 4, lessThanMode=true) // triggers if a specific log message appears less than 4 times in a 15-minute
 window .withLogMessageThreshold("MY_LOG_MESSAGE", 10, severity = AlertSeverity.Warning) // Raise warning alert in PagerDuty after 10 logs
 containing `MY_LOG_MESSAGE` are detected .withLogMessageThreshold("MY_LOG_MESSAGE", 2) // Raise an alert when a service generates two or more
 logs containing the specified MY_LOG_MESSAGE within a 15-minute timeframe. 

The number of all http requests to alert on

 
.withTotalHttpRequestThreshold(1000) # alert when 1000 requests are received in a 15-minute window 

True if you are defining alerts for something that is NOT a standard microservice
