Gaps in Cacti graph

[adsanchez]

Hi,
I have seen in some of the graphs some gaps, i´ve tried some thing and it´s not a problem with the poller, i changed from cmd to spine and the gaps continue, i have 1 cron and what i see it´s that it´s not updating the rrd correctly and i don´t know how to fix it
I apreciate the advices!

This is an example of the cacti log

Hi thanks for the reply

Some examples of Cacti Log:
CMDPHP: Poller[0] WARNING: SNMP GetNext Timeout for Host:
CMDPHP: Poller[0] Host[84] ERROR: HOST EVENT: Host is DOWN Message: SNMP not performed due to setting or ping result., ICMP ping Timed out
CMDPHP: Poller[0] WARNING: SNMP GetNext Timeout for Host:'x.x.x.x', and OID:'.1.3'
CMDPHP: Poller[0] Host[77] DS[228] WARNING: Result from SNMP not valid. Partial Result: U

Snmpget
iso.3 = No Such Object available on this agent at this OID

[gandalf]

You've got it!
Usually, a target conforming to SNMP standards should return the next available object when doing a GETNEXT for .1.3
Your target is not the first that does not conform _really_ to that. You may want to change the ".1.3" in lib/snmp.php by any OID that works for you. You should be warned: this change will apply to ALL targets - you need to find an OID that works for all your targets. Or you might select a different downed host detection method.
