RUM JS sends the events to APM server but some events are not stored

[gabrielslach]

I can observe that RUM JS is able to send all the events I need to APM server.
However, some events are dropped (not reflected in Kibana).

For added information, I disabled the auto instrumentation in RUM so I only log necessary events.

Any suggestions on how to find the issue?

Hi @gabrielslach,

• Could you share your RUM js initializations snippet?
• Have you checked the payload of each of the events to make sure they contain the transactions that you would expect to see in Kibana? To do so, you need to do this first: https://www.elastic.co/guide/en/apm/agent/rum-js/current/troubleshooting.html#disable-events-payload-compression
• Do you have any examples of transactions that are not being reflected in Kibana?

Thanks,
Alberto

Hello @devcorpio ,

RUM config
elasticApm.init({ serviceName: '', serviceVersion: '', instrument: false, logLevel: 'error', apmRequest: ({ method, headers, payload }) => { home.fetch(ENDPOINTS.ANALYTICS, { method, headers, body: payload, }); return false; }, });

Event Payload that is not reflected to kibana. I ommited some details like the tags.
{"metadata":{"service":{"name":"-","version":"-","agent":{"name":"rum-js","version":"5.16.0"},"language":{"name":"javascript"}}}} {"transaction":{"id":"fcae9fe9f55a8331","trace_id":"310c98878e554d3ce31f4abcd9c27170","name":"-","type":"custom","duration":2,"context":{"tags":{},"page":{"referer":"-","url":"-"}},"span_count":{"started":1},"sampled":true,"sample_rate":1}} {"span":{"id":"f01b15f048ce1da6","transaction_id":"fcae9fe9f55a8331","parent_id":"fcae9fe9f55a8331","trace_id":"310c98878e554d3ce31f4abcd9c27170","name":"","type":"custom","start":0,"duration":2,"sample_rate":1}}

Is there a similar issue? What might be the causes of the transactions not getting to kibana intermittently?

Hi @gabrielslach,

We are not aware of a similar issue.

A few questions:

• is this problem just happening with your custom transaction?
• if you go to Kibana APM services UI and filter by transaction type "custom" sometimes you don't see the sample, is my understanding correct?
• have you checked in Kibana Discover to see if the transaction is there?
• have you checked the traces-apm.rum- index? More info here
• what version of the Elastic Stack are you using?
• Are you using APM server standalone or APM integration? What version exactly?
  • if you use APM standalone you may want to check the logs to see if something is happening in the intake. See this
  • if you are using APM integration, please check this

Thanks,
Alberto
