How to interpret PHP-FPM listen queue numbers from status page?
I've noticed that my site becomes a little bit slower during peak traffic time. I've been watching my server's CPU and memory usage. Memory consumption is very low, so I ruled it out. CPU is also moderate. It's hanging at around 50~60%.
One thing I noticed from PHP-FPM status is that its listen queue numbers are maxed out as follow.
process manager: static
start time: 10/Nov/2018:01:49:58 +0000
start since: 186809
accepted conn: 2127578
listen queue: 0
max listen queue: 127
listen queue len: 128
idle processes: 9
active processes: 3
total processes: 12
max active processes: 13
max children reached: 0
slow requests: 0
How do I interpret max listen queue and listen queue len?
My best guess from googling is that there is one item in the queue that is waiting for PHP-FPM to process (127 vs 128). Is that correct?
If that's correct, one thing that does not make sense is that there are 9 idle processes. What stops my PHP-FPM processes queue when there are enough idle processes?
