# Nethealth HTTP Check
|
|
|
|
The nethealth binary performs a quick HTTP GET download speed check
|
|
Key Features:
|
|
- Shell-script friendly - returns a non-zero exit code on timeout or corruption or bandwidth threshold failures
|
|
- Timeout configurable to abort the test early (for super slow links)
|
|
- Can compare actual bandwidth against a command line minimum bandwidth parameter and return a non-zero exit code.
|
|
- Corruption check - can download a checksum file and compute blob checksum and compare.
|
|
- Configurable object URL for non-GCE environments
|
|

## Generating content files
|
|
|
|
The following steps can be used if you wish to generate content files for different sizes.
|
|
|
|
Assumptions: openssl installed and 64MB blob
|
|
|
|
```
|
|
$ openssl rand -out 64MB.bin 67108864
|
|
$ openssl sha512 64MB.bin > sha512.txt
|
|
$ cat sha512.txt
|
|
SHA512(64MB.bin)= 9abddc26a6bda88864326bdc8130f0653562669fcc7f617b26a53ea73781d5cb2eb9418fde53a5743c86aa2c493aeb8933d829a812d275c2fc4ecd84427999bf
