How to know number of jiffies collected by CPU collectd plugin

[Suraj Bora]

We are intermittently seeing CPU value collected by Collectd CPU plugin is very less and in next collection its increasing drastically.

We are collecting data every 10 sec. 

From below link it seems it is not guaranteed that number of jiffies collected will be 100 in one sec. 

https://collectd.org/wiki/index.php/Plugin:CPU

Query: 

1. How to know how many jiffies collected by collectd cpu in one sec. Are there any logs where we are logging this information or way to enable such logging.

2. What is max number of jiffies  collectd CPU plugin can collect.

Here is exact values we are seeing in bulk stats:

cpu.1.idle,749190415 

cpu.1.idle,749219444 29029

cpu.1.idle,749227190 7746

cpu.1.idle,749277343 50153

cpu.1.idle,749306293 28950

cpu.1.idle,749335244 28951

last column is difference between two consecutive values. For this we can see value in third row is very low 7746 and in forth row is very high 50153.
