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; Sumo Logic neither the Essentials nor the Enterprise Suite package lists a price on the pricing page; both link to Contact Sales
  • They diverge on capability: Azure Monitor covers Log collection, Sumo Logic covers Log aggregation.
  • Prices and features above were last checked on 30 August 2026.

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

Sumo Logic

  • Neither the Essentials nor the Enterprise Suite package lists a price on the pricing page; both link to Contact Sales
  • Quoted per GB figures assume an annual commitment, an average of 1 GB of log ingest per day and a US deployment region
  • Pricing varies by the AWS deployment region chosen, so the same volume costs differently in Dublin, Frankfurt, Sydney or Tokyo
  • Flex pricing bills per TB scanned rather than per GB ingested, so query activity drives the bill
  • Feature activation is subject to minimum volume, minimum user counts and service requirements confirmed at the time of the transaction
  • The API is limited to four calls per section, ten concurrent in-flight requests, and query processing times out after two minutes
  • Self-serve credit card purchase is capped at $25,000; larger purchases must go through sales or a reseller
