Where each one falls short

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

Mezmo

  • No pricing tiers or dollar amounts published on pricing page
  • No named plans available to compare
  • Pricing model not transparently disclosed upfront

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
