Squid Efficiency Analyzer

Squid Efficiency Analyzer lets you open a log file and kick off the analysis right away. You just sit back and wait for the results to pop up! They’ll show up in a detailed table and also in a summary text field. And if you need to save that info, you can easily export the results to a file.

How It Works

This nifty tool checks every single line of your Squid log file. It tracks how often different cache codes happen and measures the traffic associated with them. After that, it breaks down the traffic from both your cache and the internet.

Handling Big Numbers

For this project, I decided to use signed 64-bit integers because they can handle large numbers pretty well. But just a heads up—if values go beyond this range, let me know! I’m not sure what to do about it yet.

Cache Codes You’ll See

You’ll get some cool codes that tell you about data from the cache:

• TCP_HIT


• TCP_REFRESH_HIT


• TCP_REF_FAIL_HIT


• TCP_IMS_HIT


• TCP_MEM_HIT


• TCP_OFFLINE_HIT


• UDP_HIT

Internet Data Codes

The tool also gives you codes for data coming from the internet:

• TCP_MISS


• TCP_REFRESH_MISS


• TCP_CLIENT_REFRESH_MISS


• TCP_SWAPFAIL_MISS


• UDP_MISS

Coding Not Considered for Efficiency

The rest of the codes? They don’t count towards efficiency:

• TCP_NEGATIVE_HIT
• TCP_DENIED
• UDP_DENIED
• UDP_INVALID
• UDP_MISS_NOFETCH
• NONE
