Changing Multi-Device SNMP settings may not work as expected

[arno-st]

I have to change the settings of many switch, passing from snmp v2 to snmpv3, so I did on all the switch physically, but on cacti I'm selecting all devices, and do an action -> change settings.
Selecting the new community, is only half done.

Even if the information is set on the device, it's not really apply.
when I go to a device I got:
SNMP Information
Host SNMP error
Ping Results
ICMP Ping Success (0.87 ms)

And I have to go to each device to do a save to be sure the new settings is apply.

Sorry Cacti 1.2.19

[TheWitness]

What version 1.2.x?

[arno-st]

Yup just give in the second post 1.2.19

[TheWitness]

I'm working on this part of the code today. In the mean time, press the Repopulate Poller Cache link when editing the Device.

[TheWitness]

Also, 1.2.x has a oush_out_hosts.php cli that'll let you do it enmass.

[arno-st]

Hmm I don't think we have the same 1.2.x branch, I can't find any push_out_hosts.php on which folder it should be ?

<cacti_dir>/cli

Download it from
https://github.com/Cacti/cacti/tree/1.2.x/cli

[arno-st]

When you said 'Repopulate Poller Cache link' you mean 'Rebuild Poller Cache'

Tha one with the warning about the time it can take to run ?

[TheWitness]

From GitHub, first switch to the 1.2.x branch, then drill Don into the code.

Or:

cd /var/www/html
git clone https://github.com/cacti/cacti.git cacti.new
cp cacti.new/cli/push_out_hosts.php cacti/cli

[TheWitness]

The time it takes to run depends on the number of graphs. How many graphs for this one device?

[TheWitness]

If it's less than 10k graphs, it should be pretty quick.
