Measure your own log first: the free profiler at logcaliper.app reads a sample in your browser, nothing uploaded. Then size every source here.
Logcaliper sizes log management and SIEM deployments. Pick the sources you collect from, set the retention and compression, and get the storage, the cluster capacity and the number of data nodes to hold it. It converts message rates and data volumes in any unit, decimal or binary, and puts any size in human terms.
Every SIEM quote turns on two numbers: the bytes per event and the events per second. Logcaliper ships measured average event sizes for 39 common products and typical event rates for 16 source categories. To measure your own, the free profiler at logcaliper.app/profiler reads a sample of your log in the browser, with nothing uploaded.
NEW IN 3.1.1:
- Measure yours: beside the average message size, a link to the free profiler on logcaliper.app, opened here or sent to a computer
- New rows under Settings, then About: a source that is missing, Rate Logcaliper, and logcaliper.app
- Adding a source to your list no longer sends the rate or the event size you set
- The privacy policy is a plain page on logcaliper.app that names every event the app sends
- The rating prompt appears at most once per version, at the end of a task
HIGHLIGHTS:
- Storage estimate for a list of log sources: retention, compression, indexing, replication, cluster capacity and number of data nodes
- Average event sizes for 39 common products, measured from more than ten million log events
- Typical event rates for 16 source categories, with the condition that drives each figure: whether Sysmon is deployed, whether flows are sampled, what the database audit policy is
- Conversion between message rates, per second to per month, and data rates, bits per second to exabytes per year, decimal or binary
- Share of an Ethernet link for any bit or byte rate
- Comparison of any data size against things you recognise, from a page of text to a gram of DNA
- Long-press a conversion result to copy it, as the number or as the whole sentence with its units
- Email export of an estimate with its list of sources
- PCI DSS retention labels from requirement 10.5.1 of v4.0.1
- Threshold, a game that teaches the scale of data and log volumes, also on the web at logcaliper.app/threshold
- Free, no account, no ads. iPhone and iPad, iOS 18 or later
Measure yours: beside the average message size on the Log tab, a new link to the profiler on logcaliper.app, which reads a sample of your own log in a browser, with nothing uploaded, and gives the bytes per event and the events per second to type in here. Open it here, where its 1.5 MB sample runs, or send the link to the computer that holds your log. An emailed estimate carries the same link.
The privacy policy is now a plain page on logcaliper.app that names every event the app sends and what each one carries. To match it, adding a source to your list no longer sends the rate or the event size you set; only the source's name from the catalogue goes.
Three new rows under Settings, then About:
• A source that is missing: write to me with the product and its event size, and it can go in the next release.
• Rate Logcaliper.
• logcaliper.app, where the free profiler reads a sample of your own log in the browser, with nothing uploaded, and gives the bytes per event and the events per second to type in here.
The rating prompt now appears at most once per version, after an estimate, a share or a copy, and never in your first session, instead of every tenth time the Log tab opened.
