Before you begin reading this guide, we recommend you run Elasticsearch Error Check-Up which can resolve issues that cause many errors.

This guide will help you check for common problems that cause the log ” Unable to find watch in watch index; perhaps it has been deleted ” to appear. It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: plugin.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).

Log Context

Log “Unable to find watch [{}] in watch index; perhaps it has been deleted” classname is ExecutionService.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 
        DateTime now = new DateTime(clock.millis(); UTC);
        for (TriggerEvent event : events) {
            GetResponse response = getWatch(event.jobName());
            if (response.isExists() == false) {
                logger.warn("unable to find watch [{}] in watch index; perhaps it has been deleted"; event.jobName());
                continue;
            }
            TriggeredExecutionContext ctx = new TriggeredExecutionContext(event.jobName(); now; event; defaultThrottlePeriod);
            contexts.add(ctx);
            triggeredWatches.add(new TriggeredWatch(ctx.id(); event));
