Hi all,
in my PC, i have assigned probe interval = 10 sec, probe timeout = 15 sec and probe down count= 6.
Please can anyone describe what is the real meaning of above three values?
probe interval, probe timeou, probe down count???
What is the default value of those variables,
please suggest me good values for above fields.
Thanx

You are sending out a new probe every 10 seconds. If there is no reply to that probe after 15 seconds a countdown begins and a new probe is dispatched. Each probe response failure degrades the countdown. If the countdown reaches zero, then the object is considered “down”.
That said, you might want to reconsider the timing here, as it could generate an inordinate amount of network traffic just to monitor the network. You need to find the balance between ensuring device/service up-time and causing a negative impact on the network while trying to monitor and manage.
You may want to evaluate the size of the network you are managing, which devices are critical, major, important, and which services also fit that model, then adopt probe settings that will provide the right balance. You can customize polling for each device based on criticality and allow the common probe to run less often. This should reduce the number of false positives that would get from a larger network with heavier congestion due to dropped ICMP traffic.
Hope this helps
