  • Ask HN: What do you monitor on your servers?
    Https://hetrixtools.com/ It's free if you don't have too many servers - 15 uptime monitors (the most useful) and 32 blacklist monitors (useful for e-mail, but don't know why you'd need so many compared to uptime). It's fairly easy to reach the free limits with not many servers if you're also monitoring VMs, but I've found it reliable so far. It's nice you can have ping tests from different locations. - Source: Hacker News / about 2 years ago
  • How to check how many resources use my website?
    You can use "htop" command to view current CPU, RAM and SWAP usage, also see which process is taking up how much of each resource. And if you want to collect data over time, you can use a monitoring agent like https://hetrixtools.com/ to monitor network, cpu, ram, disk access etc all of the time. Source: over 3 years ago
  • Does ManageWP have a feature to monitor SSL Uptime?
    HetrixTools about the best free service I've used that includes that. Source: over 3 years ago
  • Is hetzner down?
    You can use hetrixtools Uptime Monitor for free. Https://hetrixtools.com Better Uptime is also good. Https://betterstack.com/better-uptime. Source: over 3 years ago
  • Xfinity is what the folks are using?
    I'm using Ziply and they have been pretty much rock solid. I have a free uptime service via https://hetrixtools.com/ and they claim that in 2022 my uptime percentage is 99.9990%. And likely some of that is when I have decided to reboot my router. Source: almost 4 years ago

  • Need advice: Java Software Architecture for SaaS startup doing CRUD and REST APIs?
    Apache Karaf with OSGi works pretty nice using annotation based dependency injection with the declarative services, removing the need to mess with those hopefully archaic XML blueprints. Too bad it's not as trendy as spring and the developers so many of the tutorials can be a bit dated and hard to find. Karaf also supports many other frameworks and programming models as well and there's even Red Hat supported... Source: over 5 years ago
