Serverwatch

Simple server monitoring with web notification.

Best suited for:

• Personal / non-critical projects that you still want to make sure it's up.
• Personal email server.

Features

• Monitor multiple services & list them in one page.
• Log monitoring data in SQLite database.
• Access uptime statistics for the pervious day/week/month from web.
• Access latest (last n minutes) monitoring log from web.
• Comes with code for checking if HTTP server is up, responding with 200 and whether response contains some pre-defined strings.
• Comes with code to check for close-to-expiration / expired TLS certificates.
• Support SMTP STARTTLS for checking email servers.

Usage

1. Open web/checks.rs

2. At the end of the file, find a piece of code like this:

  http_and_tls!(0<<4, "maowtm.org");
  http_and_tls!(1<<4, "paper.sc");
  http_and_tls!(2<<4, "static.maowtm.org");
  http_and_tls!(3<<4, "localhost");
  smtp!(        4<<4, "gmail-smtp-in.l.google.com");

3. Remove them, and replace with code that check your servers.

   The macro http_and_tls! and smtp! takes two argument: a unique check id, and the domain to check. Check id can be any number you choose, as long as it is unique for each check. Internally, http_and_tls! creates two checks, one with the provided check id, another with the provided check id + 1. Hence I used n<<4 to ensure that no two checks get assigned the same check id accidentally.

4. cargo build --features 'web' --release

5. Run target/release/web. This will open a web server as instructed in web/Rocket.toml.

TODOs

• Add more checks
