SNMP Get Timeout and how troubleshoting system stats

[L0gRuS]

Good day!

Some days ago i founded 2 problems on my cacti system.

First problem:
In cacti log i have next rows.

Code: Select all

 CMDPHP: Poller[0] WARNING: SNMP Get Timeout for Host:'127.0.0.1', and OID:'.1.3.6.1.2.1.25.2.3.1.5.48'
 CMDPHP: Poller[0] WARNING: SNMP Get Timeout for Host:'127.0.0.1', and OID:'.1.3.6.1.2.1.25.2.3.1.6.48'

But i cant found graphs with this oid. i check poller cache and snmp cache but nothing. Cacti display 0 results. How i can found graph with this oid?

Second Problem

In cacti log i have next rows

SYSTEM THOLD STATS: Time:0.0593 Tholds:27 TotalHosts:5 DownHosts:0 NewDownHosts:0
SYSTEM STATS: Time:29.3618 Method:spine Processes:4 Threads:2 Hosts:6 HostsPerProcess:2 DataSources:229 RRDsProcessed:139

Fews month ago i has 10 seconds.. now 29.. How i can find slow hosts and graph?
