I am receiving the following error when using your config:

Error in plugin [inputs.snmp]: initializing table unifi: initializing field ifDescr: translating: exec: "snmptranslate": executable file not found in $PATH

I did see the other thread here but the solution was clear.

Any help would be greatly appreciated.

Ubuntu Server 16.04

I was getting a templating error with the HP LaserHet dashboard in Grafana 5.0. I fixed the issue by changing line 5104 of hp-laserjet-dashboard.json to

"query": "SHOW TAG VALUES FROM \"ifTable\" WITH KEY = \"ifDescr\" WHERE \"agent_host\" =~ /^$host$/",

I don't know how else to submit this fix, sorry.

Nice work!

Would it be possible to show the ESSID instead of "ath0", "ath1" and so on, for the "unifiVapName" ?

Hello, hasn't found unifi mibs in update blog (probably buried too deep)
Here is official links AFAIK:
http://dl.ubnt-ut.com/snmp/UBNT-MIB
http://dl.ubnt-ut.com/snmp/UBNT-UniFi-MIB

I added the content of "telegraf-inputs.conf" to /etc/telegraf/telegraf.conf, and tries to restart telegraf.

Being a total newbie on telegraf, grafana and influx - I have no idea how to troubleshoot it. Would appreciate any help/guidance :)

I am getting data for all panels except for 'Client Connection Quality'. I see the query begins with:

SELECT last(\"unifiVapCcq\") / 10 FROM \"unifiVapTable\"
However I have no unifiVapCcq field in unifiVapTable. Here is a sample write point (some values obscured):

> unifiVapTable,agent_host=unifi01,host=host001,unifiVapName=ath0,unifiVapRadio=ng unifiVapBssId="80:2b:a2:3a:44:2",unifiVapChannel=11i,unifiVapEssId="ssid001",unifiVapExtChannel=0i,unifiVapNumStations=3i,unifiVapRxBytes=3226148884i,unifiVapRxCrypts=108140i,unifiVapRxDropped=108610i,unifiVapRxErrors=108610i,unifiVapRxFrags=0i,unifiVapRxPackets=22051767i,unifiVapTxBytes=1317084149i,unifiVapTxDropped=62653i,unifiVapTxErrors=0i,unifiVapTxPackets=38486213i,unifiVapTxPower=20i,unifiVapTxRetries=1305891i,unifiVapUp=1i,unifiVapUsage="user" 1543803019000000000

I'm unsure if the missing comma following unifiVapRadio=ng is intentional (could this be the separation between tags and fields?). This is consistent across all the write points I see.

I am using the same MIBS, including UBNT-UniFi-MIB, as in this repository.

This could be something missing in the inputs. This could also be SNMP on my APs (2x UAP-AC-Lite 3.9.54.9373, GEN2). I could use help here.

Evening,

I posted this but my internet dropped out as I did it. In Grafana I get the following error... I don't suppose you know why. Cheers.

Templating init failed

Hi,

After starting telegraf with your configuration and mibs, I get these error messages:
2017-06-15T13:56:16Z E! Error in plugin [inputs.snmp]: agent 192.168.1.1: gathering table ifXTable: performing bulk walk for field ifConnectorPresent: Request timeout (after 3 retries)
2017-06-15T13:56:26Z E! Error in plugin [inputs.snmp]: agent 192.168.1.1: gathering table ipSystemStatsTable: performing bulk walk for field ipSystemStatsInReceives: Request timeout (after 3 retries)

The grafana dashboard shows most metrics, however both Interface Traffic graphs are empty.

Any idea what might be causing this?

Hi,

I saw your post on the Ubiquiti forums and it helped a lot.

I noticed, that all the SNMP tables did lack the sysName information.

If you add inherit_tags = ["sysName"] to each table, you can get the name of the Device from Unifi into your series to group by device name or so on

   #  Ethernet interfaces
   [[inputs.snmp.table]]
     oid = "UBNT-UniFi-MIB::unifiIfTable"
     inherit_tags = ["sysName"]
     [[inputs.snmp.table.field]]
       is_tag = true
       oid = "UBNT-UniFi-MIB::unifiIfName"

I may be doing something really stupid. But I added two of my AP's as below in the telegraf.conf however I can't find where to see the AP's. In Grafana it just lists NONE.

Am I doing something wrong? Cheers.

UniFi APs (Gen 2/Gen 3)

[[inputs.snmp]]

List of agents to poll

agents = [ "172.16.2.128:161", "172.16.2.129:161" ]

The only downside I'm seeing with using this is that it creates a lot of different measurements in my influxdb. Is there a way to make them all under one measurement like UBNT or something and not hrDeviceTable IfTable, IfXTable, etc?

is it possible to update the json for influxdbv2?

I'm using EdgeMAX EdgeRouter 4 v2.0.9-hotfix.2

Here is the uptime showing on the device.

Your Grafana's Dashborad Uptime section query result is 1882461 by below SQL inquiry.

`SELECT "sysUpTime"  / 100 FROM "snmp.EdgeOS" WHERE ("agent_host" =~ /^$host$/) AND $timeFilter

So, which part is going wrong to caused this issue?

telegraf related config

  [[inputs.snmp.field]]
     name = "sysUpTime"
     oid = "HOST-RESOURCES-MIB::hrSystemUptime.0"

The HOST-RESOURCES-MIB.txt file in telegraf docker was copied from EdgeRouter /usr/share/snmp/mibs folder

hrSystemUptime OBJECT-TYPE
    SYNTAX     TimeTicks
    MAX-ACCESS read-only
    STATUS     current
    DESCRIPTION
        "The amount of time since this host was last

        portion of the system."
    ::= { hrSystem 1 }

I also tried inquiry SNMP OID

below OID comes from https://github.com/grafana/jsonnet-libs/tree/master/ubnt-edgerouter-mixin

https://github.com/grafana/jsonnet-libs/blob/02db06f540086fa3f67d487bd01e1b314853fb8f/ubnt-edgerouter-mixin/snmp_generator/snmp.yml#L1036C25-L1036C25

    help: The amount of time since this host was last initialized - 1.3.6.1.2.1.25.1.1

OID 1.3.6.1.2.1.25.1.1 corresponds to HOST-RESOURCES-MIB::hrSystemUptime.
hrSystemUptime is similar to sysUpTime in the SNMP MIB-II, but it's part of the Host Resources MIB. It represents the amount of time since the host was last initialized.

iso.3.6.1.2.1.1.3.0 is the full OID for the sysUpTime object, representing the time since the last system start-up.

telegraf@abf4573b2ca9:/$ snmpget -v2c -c ouzycn 192.168.1.253 1.3.6.1.2.1.1.3.0

According to the below info, I think what you were using hrSystemUptime is correct.

The difference between the OIDs 1.3.6.1.2.1.25.1.1 and 1.3.6.1.2.1.1.3.0 in SNMP lies in their origin and specific use cases:

1. OID 1.3.6.1.2.1.1.3.0 (sysUpTime):

• This OID comes from the SNMP MIB-II (Management Information Base II) standard.
• sysUpTime represents the time since the network management portion of the system was last re-initialized.
• It is widely used for general network management purposes.
• The uptime reported by sysUpTime resets to zero whenever the SNMP agent (the network management part) is restarted, which can happen independently of the host system's restarts or reboots.
• It is a part of the System group in the MIB-II.

2. OID 1.3.6.1.2.1.25.1.1 (hrSystemUptime):

• This OID is from the Host Resources MIB.
• hrSystemUptime provides the amount of time since the host (the entire system) was last initialized.
• It's more host-centric and is often used for tracking the uptime of the actual computing device (server, workstation, etc.) rather than just the network management aspect.
• The uptime reported by hrSystemUptime resets only when the host system is rebooted or restarted.
• It belongs to the Host Resources MIB, which includes more detailed information about the host's resources like storage, installed software, and device performance.
• In summary, while both OIDs report uptime, sysUpTime is specific to the network management subsystem and can reset independently of the host system, whereas hrSystemUptime is specific to the host system's uptime and resets only when the entire system restarts. This distinction is important when monitoring the uptime for network devices vs. the actual hosts/servers they are part of.

In summary, while both OIDs report uptime, sysUpTime is specific to the network management subsystem and can reset independently of the host system, whereas hrSystemUptime is specific to the host system's uptime and resets only when the entire system restarts. This distinction is important when monitoring the uptime for network devices vs. the actual hosts/servers they are part of.

Hey,

would you rather suggest to merge the configs or run two instances. I struggle to merge them both - how did you manage it?

Thanks for all your work!

I've followed all of the instructions and the dashboard is almsot working 100%, but i cant get the graphs for Interface Traffic and Interface Traffic Distribution populate.

Any input? @WaterByWind

UAPs with 3.9.x firmware, at least Gen 3 and possibly Gen 2, no longer display properly in this dashboard.

This firmware changed from tinysnmp to the more-standard net-snmp which requires an updated telegraf inputs stanza with this dashboard to collect the needed metrics.

This update is forthcoming.

Hello,

just a small error in log about a module not found:

Maybe I forgot to install something ...

Please could you provide more information on how you managed to get Telegraf running on your EdgeRouter?

I have done a fair amount of Googling and I'm struggling to find any information on how to do this and there don't appear to be any binaries as requested here

snmp.UAP.sysUptime returns seconds. It is divided by math / 100 on the dashboard.

Hi,

Being a total novice in setting up SNMP stuff, I am now reaching out to you.

I have set up the EdgeOS device (ERX SFP) with following config:

snmp {
    community public {
        authorization ro
        network 192.168.2.0/24
    }
    listen-address 192.168.2.1 {
        port 161
    }
}

But I can't manage it to work. I have placed telegraf-inputs.conf info /etc/telegraf/telegraf.d/ and installed the dependencies (net-snmp and net-snmp-utils) in order to remove the error messages about "snmptranslate not found in $PATH".

Now I get the following instead:
telegraf: 2017-05-22T07:49:07Z E! Error in plugin [inputs.snmp]: took longer to collect than collection interval (5s)

Being a novice in SNMP stuff (as mentioned earlier) I would really appreciate some pointers.

NOTE:
I am running CentOS 7 core.

I managed to get this running after compiling all the latest versions of golang, telegraf, etc. Is there any way you've found to display traffic totals for interfaces? The traffic stats on the edgerouter suck since they reset after a few hours of inactivity.

Hi @WaterByWind ,

New to Grafana/Telegraf/Influx. Having some problems with SNMP with the edgerouter dashboard. I have everything configured properly i believe. Another set of eyes and any suggestions would be great.

I am wandering if you know the answer to this. UBNT have some .mib files. Do I need to save these the /usr/share/snmp/mibs folder for this to work?

Your edge router script also works perfect with my USG PRO.
Thanks !! awesome job.
