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; Loggly the free Lite plan caps ingest at 200 MB per day with 7 day retention
  • They diverge on capability: Azure Monitor covers Log collection, Loggly covers Log aggregation.

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

Loggly

  • The free Lite plan caps ingest at 200 MB per day with 7 day retention
  • API access and archiving to Amazon S3 start on the Pro plan at $159 per month billed annually
  • Federated identity management is an Enterprise feature, starting at $279 per month billed annually
  • The Standard plan at $79 per month is limited to 1 GB per day and 3 source groups
  • Maximum retention is 90 days and only on Enterprise; Standard is fixed at 15 days
