Web Server Monitor Software

[rick19810]

Does anyone know of an easy, local application what will check that the
Blue Iris web server (or any web server, for that matter) is running?
There have been several incidents where the computer I have BI running on
has gone down, and since I don't routinely check that device, it can be
down for a while without me knowing. (And before you ask it, yes, it's on a
UPS).
I wrote a little VB program that runs on the computer I use everyday, but
I'm less than thrilled with how it's working.
The requirements:
The program/app shall:
- monitor port 81 on my BI device, and notify me when it's status changes.
- run on my local home network (I don't want a web-based solution).
- run on a PC, Android, a Hubitat hub (even though that's not really what
that hardware is for), or any other cheap hardware.
- send a notification by email, text message, or a Android notification to
my phone.

I did try one Android app, pointed it to my BI server's external address,
and got it to report that it was active.
All fine, except when I tested it by shutting down BI, and then by shutting
down the device, it still said it was active. Not much help.

Has anyone gone done this rabbit hole and found a decent way to check on
the BI web server?

You could run a script to see of the BI system is up and then test to see if port 81 is open. If not run another script to use mailsend-go to alert you, either email or sms. You would have to run such as a cron job. I have done similar using nmap to test systems and ports.

Thanks, Lou. Unless I'm not digging deep enough, this has the same issue that I have with the VB program I wrote: dealing with the password. I want something where I don't have to enter a password it each time I kick off the program without committing the security sin of saving it.

OK, I guess I don't understand your use case. I had a couple of scripts (back in the day) and one scanned the network every hour during the day. Emailed me if it spotted anything new. Another looked for systems left on at night. Both ran as cron jobs, as user (me).
Good luck, if you find something, please let the forum know.

Saw this and came to suggest Uptime Kuma as well. Super easy to use if you're just monitoring ICMP, a TCP port, web page, etc.

If you ever need something fancier, Zabbix is a good solution, but it's overkill unless you need to monitor CPU/GPU/RAM/etc. as well as the easy network stuff.
