Unfortunately, it is too many for Uptime Kuma currently.

I am thinking the monitor list have to be lazy loading in order to fix the issue.

Some more related problems:

• Not possible to add a list of more than 400 internet addresses by one import process! Returning a lost connection error. So I broke my items list into some smaller json files with around 150 addresses and then imported them one-by-one 😫
• Not possible to add more than 1200 items! Around this number, it does not accept any other json file. The upload process takes for a long time until you get tired and close the tab of browser!
• By ~1000 items, every 10, or 15 seconds, it shows a red lost connection error and tries to retrieve all those address again in the web console.

May I ask what 400+ monitors are for?
I could imagine any commercial applications etc. but then again probably other tools would make much more sense.

Here a suggestion for a solution that might or might not work for you to avoid hitting this current limitation:

You could separate/group your monitors and just run then multiple uptime-kuma docker instances. Just on different ports.

So eg. you have total of 400 monitors, 100 are in LAN, 150 are websites, and another 150 are diverse…

So it would be like this:

ip.address:3001 = lan monitors
ip.address:3002 = website monitors
ip.address:3003 = diverse monitors

Again, just a work around - not necessarily applicable in your situation, but maybe it is.

Edit: oh i misread/ misunderstood your initial post… anyway; the above might be helpful for others.

@chakflying you did not add this issue to #3515. Was this intentional?
