Which line in the wall of red actually matters? A service is flapping, a channel is filling with people asking for an update, and the answer sits four screens back in output that all looks the same. The Log Analyzer takes the chunk you paste and tells you, in plain English, what it thinks broke and what to check next.
Log Analyzer returns a plain English read of the log block you paste: the likely trigger, which lines are only downstream noise, and the checks worth running next. It connects to nothing and confirms nothing for you.
What is Log Analyzer?
The Log Analyzer is a reading tool, not a monitoring one. Paste a slice of log output, pick a model from the selector, and it comes back with what those lines are saying: which error is the trigger, which are downstream noise, and what usually causes that pattern. It does not tail a file, watch a container or reach into your logging stack. Everything it knows comes from the text in the box.
Where it helps
- Turns an unfamiliar log format into something readable in one pass.
- Good at separating the first failure from everything it knocked over.
- Useful for handing an incident to someone who was not on the call.
Where it stops
- It only sees the lines you paste, so a bad slice earns a confident wrong answer.
- It cannot check your metrics, config or database.
- Nothing is verified, so every finding is a lead rather than a diagnosis.
How Does Log Analyzer Work?
Paste the log slice, pick a model, then open the advanced options. This panel is shared with the deployment generators, so only part of it fits here. Set Output to Explained and Detail to Detailed. Name the Platform / Tool when you know it, Kubernetes for a pod log, and set Environment to Production when that is where the log came from. Leave Config File, Script and Pipeline alone, because those belong to the generators. Include Security Notes is already on, which earns its place the moment a log shows failed sign in attempts.
How Much Log To Paste
The paste decides the answer. A thousand lines of steady state noise is worse than thirty good ones.
| Include this | Why it helps |
|---|---|
| The lines before the first error | The trigger usually sits upstream of the loudest line |
| Full timestamps | Ordering and gaps are half the story |
| The stack trace in one piece | A cut trace hides the frame that matters |
| What you expected to happen | It separates a real fault from normal chatter |
Strip the secrets first Logs carry tokens, connection strings, session ids and customer addresses. Redact them before pasting, exactly as you would before attaching a log to a public ticket.
A Container That Kept Restarting
A checkout service was restarting every few minutes. The paste was the thirty lines around the first failure, with Platform / Tool set to Kubernetes, Environment set to Production and Output set to Explained. The input opened like this:
03:12:07 ERROR db pool exhausted after waiting 30000ms
03:12:07 WARN retry 3 of 3 failed for checkout-api
03:12:08 INFO shutting down, liveness probe failedThe reply opened with "Primary cause: connection pool exhausted at 03:12:07. The liveness probe failure after it is a consequence, not the trigger ..." and went on to suggest checking connection limits and slow queries before probe timing. Separating the trigger from the wreckage is what saves the time.
EizTools is free to use and asks for no account, and its library of AI tools keeps growing, each one built for a single job. You choose the model per run from the selector. When the notes around an incident run longer than the log itself, the Text Summarizer cuts them down to something you can actually paste.
Frequently Asked Questions
Does Log Analyzer connect to my logging system?
No. It reads only the text you paste. There is no agent, no file tail and no link to your cluster or cloud account, so nothing reaches the tool except the lines you choose to hand it.
Which log formats does it handle?
Plain application logs, JSON lines, web server access logs, container output and stack traces all work. Structured formats read best, but a messy mixed dump is usually still enough to name the first failure.
How much should I paste at once?
Enough to cover the window around the failure, from the lines before the first error through to the crash. A few dozen lines with timestamps beat a thousand lines of ordinary traffic.
Can I trust the cause it names?
Treat it as a lead. It reasons from the text alone, with no view of your config, metrics or database, so confirm the finding against the real system before you change anything in production.
Reading logs is a skill and the Log Analyzer does not replace it. What it does is get you to a shortlist faster, on a night when the format is unfamiliar and you are tired. Paste the window around the failure, set Output to Explained, and work from what comes back.
