Discovery Process running high on a 2 host proxy

[mellis]

Good Evening

I am in the process of setting up a new data center, it is a aws data center. We are using the 4.4.10 version of the proxy with a 4.4.10 server, that also has ~25 other proxies. We got the network setup and install the agent on the proxy and one other host in the data center. All looked good so we are mapping out the discovery rules and actions for the solution.

After about 4 or 5 days I start to see an alert on my central; dashboard for discovery processes on the proxy running high.

Zabbix discoverer processes more than 75% busy

All setting are default

# StartPollers=5
# StartIPMIPollers=0
# StartPreprocessors=3
# StartPollersUnreachable=1
# StartTrappers=5
# StartPingers=1
# StartDiscoverers=1
# StartHTTPPollers=1
# StartDBSyncers=4
# CacheSize=8M
# HistoryCacheSize=16M
# HistoryIndexCacheSize=4M


Any one have a clue as to why this would run high?

Good morning,

Please check proxy configuration file zabbix_proxy.conf for setting StartDiscoverers

Also check what Delay have you set for the Discovery rules and make it reasonable (e.g. 3600 seconds) if it is very low.

One discoverer process can run only one discovery rule at a time. When whole network segment from one rule is scanned, it takes the next rule.
If you have multiple discovery rules configured to be run by this proxy then you should have at least the same amount of StartDiscoverers configured.
