Nagios Support Forum

Hi Support Team,

Customer want to below report for network devices from Nagios XI monitoring tool.

Requirement – Report require for NTP time sync is working fine in my all network devices on daily basis.

Let me tell you, we are doing monitor customer switch, firewall,Router, AP and Wireless network devices through Ngaios XI monitoring tool.

So customer want to above report so can you tell us that is there any feasibility available in monitoring tool to monitor Network devices NTP service through Nagios XI monitoring tool.

If feasibility is available in Monitoring tool so please share steps that how can we add NTP service in monitoring tool for Network devices(switch, firewall,Router, AP and Wireless).

And also let us know is there any Agent/SNMP need to install on network devices for getting NTP service data through Agent/SNMP.

And also let us know what plugin we can use for taking NTP services data of network devices and what will be command line syntax.

So please share full details that how can we enable NTP service monitoring in Nagios XI monitoring tool for network devices.

Thanks,

Hi,

There is a plugin called check_ntp_time that will do what you require. It can be
run using NCPA. So that could be a solution for anything running Linux and a similar
solution for Windows. It sounds like you are monitoring with SNMP - is this correct?

The best way to give you instructions is for you to tell me how you are monitoring things now.
For example NRDP, NRPE, NCPA and/or SNMP ? Probably the easiest way to do this is if you
send me a System Profile.

To send us your system profile.
1. Login to the Nagios XI GUI using a web browser.
2. Click the "Admin" > "System Profile" Menu
3. Click the "Download Profile" button
4. Save the profile.zip file and share this in a private message and then reply to this post to bring it up in the queue.


Thanks

Hi Support Team,

Thanks for your response.

Note: Yes, We can monitor through SNMP because we want to monitor NTP service for Network devices(switch, firewall,Router, AP and Wireless).

We are monitor NTP service for Network devices so as per my knowledge we can use SNMP not any Agent right.
Share solution for Network devices that how can we monitor NTP service for network devices through Nagios XI monitoring tool.
And also share what will be command line syntax we can use for adding NTP service.
Please find attached system profile and check.

Thanks,

Hi,

The ability to monitor NTP status for the network devices (routers, switches, etc) through SNMP depends
on the device manufacturer. For each device you would have to go through the corresponding
MIB file to see if there is an OID that gives you the NTP status. For example a particular Huwaei
device I looked at has an OID hwNtpState that provides this information. Alternatively I came
across some Cisco devices that didn't have this information available.

Here is some good information: If you get to the point where you are trying to monitor a specific OID for a device and are having
trouble getting it configured please let me know.

Thanks

Hi Support Team,

Thanks for your update.

Can you tell us how we can monitor NTP sync time for network devices?.

Is There any method so that we can add service in monitoring tool and know whether all our networks devices NTP time are syncing with NTP server or not.

If Network devices NTP time doesn't sync with NTP server then we get an alert from Nagios XI monitoring tool.

As we are monitor NTP-Time-Sync for servers through Nagios XI monitoring tool using NCPA agent, as we have attached snapshot for your reference in attached folder.

Is there any feasibility of this type available in Nagios XI that we can add monitoring of this NTP-Time-Sync service in Nagios XI monitoring tool for network devices as well.

If possible for Network devices then please let us know the steps for adding NTP-Time-Sync monitoring in Nagios XI monitoring tool for Network devices.

Basically customer want to monitor that Network devices NTP time are syncing with NTP server or not as per define threshold value if not then customer will get alert from Nagios XI monitoring tool that this device NTP time are not syncing with NTP server .

Thanks,

@gsmith is correct on this, each make/model will be different (even from the same vendor sometimes) depending on the device. The first step is to find the make/model of the devices, the second is to find the OID from the vendor/their documentation/or their MIB files (that you would get from the vendor) that meets your needs (NTP sync status or even the current device time). It is up to the vendor if they even allow you to monitor those through SNMP on that specific network device. Then you could use those OIDs in the SNMP wizard to monitor them.

Any plugins are usually make specific as well, for example I found this one for Cisco:

https://exchange.nagios.org/directory/P ... ch/details

But those OIDs that the plugin is using are not likely to work on any other brand or even some Cisco devices that use different OIDs.

Hi Support Team,

Thanks for your update.

As discussed with network team and got to know that HP network devices NTP sync time have to monitor through Nagios XI.

Thanks,

Hi,

So were you able to set up the HP network devices?

Thanks

Hi Support Team,

Right now we are added availability in monitoring tool for HP network devices through Ping but customer want to monitor HP devices NTP-Time-Sync through Nagios XI monitoring tool and and also requested for performance monitoring .

So please help us to set up monitoring for HP network devices.

Thanks,

Hi

Are the HP devices Linux or Windows based so you can use the NTP plugin?

Or were you going to use SNMP to monitor them?

Thanks
