The short version

  • Each has a real cost: Azure Monitor billed per GB ingested across three separate log plans, Auxiliary, Basic and Analytics, so the plan chosen changes the rate as much as the volume does; Kibana requires Elasticsearch; it is a front end for data held there rather than a standalone analytics tool
  • They diverge on capability: Azure Monitor covers Log collection, Kibana covers Data visualization.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Azure Monitor

  • Billed per GB ingested across three separate log plans, Auxiliary, Basic and Analytics, so the plan chosen changes the rate as much as the volume does
  • Only the first 5 GB a month of Analytics logs is free per billing account
  • Retention beyond the base period is charged per GB per month, up to 2 years interactive and 12 years long term
  • Log queries and search jobs are billed per GB scanned, so investigating an incident costs money
  • Alert rules are billed per time series for metrics and by execution frequency for logs
  • The pricing page shows placeholders rather than rates until a region and currency are chosen

Kibana

  • Requires Elasticsearch; it is a front end for data held there rather than a standalone analytics tool
  • Self-managed means running and scaling the Elastic stack yourself
  • Cost is not Kibana's own; it follows whichever Elastic deployment sits underneath
