Hi, We Have 1 proxy. I faced "proxy can't send data fast enough" when I switch Zabbix proxy from active to passive! I did that because active proxy doesn't support connecting to 2 different Zabbix servers at the same time. Finally, we had to switch to "active mode" due to the problems that were cause by the delays! PS: It's totally OK that your videos are 30 minutes length. I watch all of them to the end :). Thanks for your efforts.

Thanks for sharing

Watched all the way, thanks for sharing and all the insight Dmitry :)

I have 3 proxies, 2 on Raspberry pi4s and 1 as a VM. Most of the connectivity issues are when I upgrade my smart switches the brief restart causes the connection to not get restarted for some brief time. made it to the end. The length of time is not as important as the content. Great job!

[@zabbixtraining]

Thank you!

[@tblich]

I made it from beginning to end. Thank you for making this one!

[@zabbixtraining]

How would you run this check (select max(id)-(select nextid from ids whre table_name = "proxy_history" limit 1) from proxy_history;) on PostgreSQL ?

[@zabbixtraining]

adopt to psql query language.

How is your mi router 4a gigabit edition? And is performance in 2.4ghz good on it?

[@zabbixtraining]

Working great without restarts :)

[@dtwoinco]

Made it to the end! Another great video, thank you!

[@zabbixtraining]

Thank you!

[@dtwoinco]

And, zero proxies right now... Waiting for my overall configuration to stabilize a bit, and then figure out where I can start to distribute some load to

[@michaelbeasley4923]

Great video. Watched the whole thing.

[@zabbixtraining]

Awesome thank you!

We have 7 proxies here. Any time we've ever had issues with them is exceeding thresholds listed in the proxy monitoring template, or an underlying infrastructure issue. They've performed well my entire Zabbix career. Since several of the mentioned common issues are network related, is it worth mentioning that nmap, ping and traceroute can be very useful?

[@zabbixtraining]

Those would be helpful to test if network works at all. But not that much for speed.

[@toddzilla]

@@zabbixtraining Correct, I was thinking more of "does my base network stack work?" I work in a heavily firewalled environment, with a few dozen admins who connect agents to our Zabbix environment. So the question of "is it the network?" comes up often. So much that I've written a distributed tool that when supplied a IP, connects to each proxy and supplies a destination IP and optional port. Each proxy pings, does an nmap on the agent port (default 10050), and executes a zabbix_get on the system.uname key and reports back the results to the tool. Basically testing all layers for my users.

[@mathiasandersson8947]

We are just starting to use Zabbix proxy and are monitoring active agents and active proxy. We only have 65 hosts with around 130 items/host and most of them reports every 5 minutes. Is it normal that the 10 seconds queue should show any items at all or does that indicate that something isnt working as it should?

[@zabbixtraining]

In a perfect conditions there should not be queue at all.

[@mathiasandersson8947]

@@zabbixtraining It also helps if all the monitored servers have the same time as the zabbix proxy/server. They were all 10s behind in time, after fixing that it looks good. I also looked at your video to the end:)

[@arutaarmor]

My Zabbix cant detects other NIC cards in the server if I unplug it. Can you please help me?

[@robertjyllhed3245]

Made it to the end of, the video, great information

[@vishwajeetkamble8553]

you are awsomeeeeeeeeeee......thanx for video....

[@kernelpanic1598]

Hello! Thank you very much for the video - like and subscribe Is data saved if zabbix server is down for 12 hours? Will the proxy transfer data to the server when the server becomes available? Will the proxy server be able to provide a "fallback node" while maintaining metrics? Will it transfer data to the server? If there is material on this topic, I would be grateful

[@zabbixtraining]

Proxy stores 1 hour of data by default, but that can be changed in configuration file. Yes, data will be sent when communication will be restored. And no there is no fallback mechanism

[@kernelpanic1598]

in the blog post on blog.zabbix.com about this video the mysql query command you pastyed there is wrong, there is a + that should be + and the limit is the letter L instead of the number 1 I spent way to much time copy/pasting this command without understanding what was the issue :D

[@simoonYT]

Hello from the very end of the movie :)

[@zabbixtraining]

Thanks for watching!

[@Undersen]

i got 7 proxies, i had problem with one that i use mysql. the database grow unexpected (40GB +) so i changed for a sqlite based.

[@zabbixtraining]

Such problem cant be caused by database engine

[@toddzilla]

Do you know what the root cause of the growth was?

[@zabbixtraining]

Most likely history daya was not deleted from databse. Housekeeper settings, db tuning, history retention settings
