Every Second, an interface will count the octets (bytes) going in and out and will present them as either ifinoctets or ifoutoctets. Grafana. I know that ifInOctets/ifOutOctets is only 32 bit and will overflow for high speeds and make my graphs look dumb, but it looks like. Explicit web proxy topologies. IPHost Network monitor uses SNMP for monitoring health and availability of devices and applications in your network. WAN optimization with web caching. Ie not using ifHCinoctets in grafana backend and ifinoctets in prtg, or other way around. I'm trying to graph network usage on my router for a specific interface using data from SNMP. Topology for multiple networks. Also, in comparison, since I am using a Solaris box, the oid for mine does not worrk, but I was able to find something similar: IF-MIB::ifInOctets.1 = Counter32: 25272632. Could you try snmpbulkwalk -c public -v2c 192.168.1.1 InOctets.2 and snmpbulkwalk -c public -v2c 192.168.1.1 ifHCInOctets.2 instead? The reference OID is: 1.3.6.1.2.1.2.2.1.10 . For example, a 10 Mbps stream of back-to-back, full-size packets causes ifInOctets to wrap in just over 57 minutes. Could you try snmpbulkwalk -c public -v2c 192.168.1.1 InOctets.2 and snmpbulkwalk -c public -v2c 192.168.1.1 ifHCInOctets.2 instead? Basic WAN optimization topology. ifHCInOctets ifInOctets. The problem is that the value fail in a minute i dont know why and the data jumps to 2 minutes, and the value is triggered to a very high value. Hey there, I'm new to grafana, and have installed the netcrunch app to link into our netcrunch data. Counter64 (SNMPv2-SMI) Module. In versions prior to BIG-IP 11.2.0, you can use objects defined in the IF-MIB SNMP management information base (MIB) to perform an SNMP poll on the BIG-IP system for network interface objects including statistics, such as ifHCInOctets or ifHCOutOctets. The high-capacity nterface counters (ifHC*Octets) should never be collected from a node that is using SNMPv1. There's a similar case to be made for e.g. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. NetCrunch Datasource - ifInOctets to bytes/sec? ifHCInOctets.2 = Counter64: 78219248 As you can read, both values actually return the same data "Total number of octest received", but we are faced with a first dilemma, you have two counters to . For example on VS3. Example topologies. I had a chance to install Net-SNMP on the SG-1100 and it returns ifHCInOctets and ifHCOutOctets: $ snmpwalk -v2c -c <redacted> 192.168.1.254 | grep -i -e inoctets. The mib2 interfaces have been found and rrd graphs created for the interfaces but despite the radios been grouped as snmp v1 and the actual counter data being stored under ifInOctets and ifOutOctets, the only graph being created by default is the ifHCInOctets & ifHCOutOctets Bits I/O (High Speed) graph containing no data. Discontinuities in the value of this counter can occur at re-initialization of the . out: . Back to rfc1573 MIB page. For example, the item of outcoming traffic is configured with net.if.in [ifHCInOctets.X] every minute and with a preprocessing: Change per second and custom multiplier x8 During initial installation, it asks whether we want to install netsnmp or not. IfInOctets=0, IfOutOctets=0 for Aruba IAP Version 6.4.2.0-4.1.1.1. if HC In Octets 1.3.6.1.2.1.31.1.1.1.6 The total number of octets received on the interface, including framing characters. pettazz Asks: SNMP differences in ifInOctets vs ifHCInOctets values I'm trying to graph network usage on my router for a specific interface using data from SNMP. I've tested a few times by using snmpwalk | grep InOctets and subtracting the values. Now it's just a matter of using which one of those. At 100 Mbps, the minimum wrap time is 5.7 minutes, and at 1 Gbps, the minimum is 34 seconds. With the current SNMP discovery implementation, if there is no entry for a certain SNMP OID, the discovery will fail by itself with the following message: Cannot accurately apply filter: no value received for macro "{#IFHCINOCTETS}". Especially CPEs and ToR switches tend to do these things on really, really slow userspace CPUs. Fortunately, there's an easy fix. To get metrics from your FortiGate in Grafana using Telegraf and InfluxDB. Received Octets : 1.3.6.1.2.1.31.1.1.1.6 (ifHCInOctets, 64-bit version) 1.3.6.1.2.1.2.2.1.10 (ifInOctets, 32-bit version). My reason for asking is because ifIn/OutOctets are counters, so what you will get when querying them is an average of bytes sent on that interface since your last poll, which will vary alot if the sampling intervals are not the same. "The total number of octets received on the interface,including framing characters. However, in Juniper's implementation, the traffic statistics that are retrieved via SNMP do not include the 14 byte Ethernet header overhead. if you want get interface counter you need get from "Counter64" (.1.3.6.1.2.1.31.1.1.1.6.x ) you couldn't see value of Counter32 The IF-MIB SNMP MIB defines the generic objects for network interface sub-layers. Where did you pull the value from? The only interfaces with 64-bit counters are the two NICs and their VLANs. version of ifInOctets. a 32 bit counter will wrap decreases. But anyway, that difference looks weird. I said arm64, as that's what bsnmpd reported, instead of Aarch64. Even with a 100% utilized 100Gb/s interface, you'll still only roll over a counter every 5.8 years or so. Before transfer: # snmpwalk -v2c -c public greco | grep InOctets. ifinoctets, ifoutoctets - interface utilization grafana vs prtg reports Ivan Azzopardi <ivanazzopardi@.> #1557 . snmpwalk . the discrepancy in the report . Everything is good, except that I ju. Enable SNMP on your FortiGate Put the following telegraf config in your /etc/telegraf/telegraf.d directory Edit the the agent IP and community string as appropriate Note: The SNMP counters wrap, the command line interface (CLI) counters do not. For example, a 10 Mbps stream of back-to-back, full-size packets causes ifInOctets to wrap in just over 57 minutes. 1 Answer Sorted by: 1 Difference is the maximal value can be set between 2^32 and 2^64. ifInOctets / ifOutOctets32graphicsifInOctets / ifOutOctetsifHCInOctets / ifHCOutOctets snmpwalk | grep InOctetstesting snmpwalk | grep InOctets 32 . Requiring that interfaces be polled frequently enough not to miss a counter wrap is increasingly problematic. The max value for the 64-bit counters is also ~4GB. IF-MIB::ifInOctets.1 = Counter32: 3195699413. Disk usage. Sushil Kumar Katre. - IfInOctets: "The total number of octets received on the interface, including framing characters. Do you have other SNMP devices to compare with?

This results into empty traffic graphs in our monitoring solution. At 100 Mbps, the minimum wrap time is 5.7 minutes, and at 1 Gbps, the minimum is 34 seconds. This object is a 64-bit version of ifInOctets. ifHCInOctets if HC In Octets 1.3.6.1.2.1.31.1.1.1.6 The total number of octets received on the interface, including framing characters. multiply by 8 to get bits/s IF-MIB::ifInOctets.2 = Counter32: 205536488. ifHCInOctets vs ifInOctets; all platforms supporting the former don't have a need to expose the latter as this has both implications to Prometheus storage and, sometimes, device CPU. Distributing WAN optimization processing. DevOps & SysAdmins: SNMP differences in ifInOctets vs ifHCInOctets valuesHelpful? With 32 bits, you can up to 4 294 967 295 octets (approximately 4.2 Go). RFC2863 defines IF-MIB and has a clear explanation on what ifInOctets and ifSpeed . Your hunch is correct - you want the 64-bit mib-2 counters ifHCInOctets and ifHCOutOctets.

The IF-MIB values that are returned for this IAP for ifInOctects and ifOutOctets are zero. IF-MIB::ifInOctets.2 = Counter32: 0. ifHCInOctets.1,IF-MIB::ifHCInOctets.2, what does these number 1,2 represent here. For example, a 10Mbs stream of back-to-back, full-size packets causes ifInOctets to wrap in just over 57 minutes; at 100Mbs, the minimum wrap time is 5.7 minutes, and at 1Gbs, the minimum is 34 seconds. Options. Following is the description for the same -. But anyway, that difference looks weird. For interfaces that operate at 20,000,000 (20 million) bits per second or less, you must use 32-bit byte and packet counters. set snmp usm user test vsid all. Rising star.

In the RFC1213-MIB it describes the values as octets received and sent on the interface, but not under which time interval. Out-of-path WAN optimization topology. I can get Mbs for any collected datapoint time by: taking it as it is, bytes/s. 2 32 = 4,294,967,296. This is SNMP basics, it's a reference to the interface table in which all interfaces are listed. IF-MIB (Force10-9.14.2.1) Nom. I am trying to check interface receive/send counters using snmp. SNMP does not return any Counter64 values for any of my OpenVPN interfaces (client or server). 1.3.6.1.2.1.2.2.1.16 - ifOutOctets returns the total number . Options. - amit singh. Logging Settings on the device send these out and Zabbix holds on to intervals, in our case 5 mins. The mib2 interfaces have been found and rrd graphs created for the interfaces but despite the radios been grouped as snmp v1 and the actual counter data being stored under ifInOctets and ifOutOctets, the only graph being created by default is the ifHCInOctets & ifHCOutOctets Bits I/O (High Speed) graph containing no data. Do you have other SNMP devices to compare with? As a demonstration, I'll transfer a 1 gigabyte file from a physical host to an ESXi guest (using vmnic2, watch the third counter). 11-02-2008 07:18 PM. And then the trick is to use correct context naming ctxname_vsid<nbr>. New Behavior ifInOctets is expressed as 32-bit unsigned integer. actual counter data being stored under ifInOctets and ifOutOctets, the only graph being created by default is the ifHCInOctets & ifHCOutOctets Bits I/O (High Speed) graph containing no data.

Ie not using ifHCinoctets in grafana backend and ifinoctets in prtg, or other way around. This object is a 64-bit version of ifInOctets. Valued Contributor. Syntaxe. They are 64 bit counters, and only roll over once every 18 exabytes. elleryweber August 31, 2017, 3:53pm #1. I'd say you shouldn't run over whole tree of SNMP OIDs, it takes a significant amount of time. Did you once have these Zero touch, Kickstart, Monitoring, Web scraping, Headless setup & Low power device Thanks for taking the time to read this post, my query is as follows. Hi and welcome, I am collecting every 2 min from my Fortigate the values from SNMP ifInOctets (1.3.6.1.2.1.2.2.1.10) and ifOutOctets (1.3.6.1.2.1.2.2.1.16). Hi Aruba Community, We would be glad if you help us solving a problem that we are facing for an Aruba IAP Version 6.4.2.0-4.1.1.1 The IF-MIB values that are ret This object is a 64-bit version of ifInOctets. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. For example: The problem I'm having is that on my networking devices, the snmp data is being sent over in octets instead of bits/bytes. . I'd say you shouldn't run over whole tree of SNMP OIDs, it takes a significant amount of time. my polling interval is once per second (just couple of ports) since I suspect my network traffic has quite a lot of microbursts which are not detectable by my other network monitoring applications. I am trying to replicate a Bandwidth in / Bandwidth Out / Bandwidth in+out sum, report from prtg with grafana v2.6.0. These 64 bit counters are already defined in the OpenNMS data collection config, and in fact are probably being collected right under your nose. Remembering zero, this provides a maximum range of 0-4,294,967,295, which means 2 32 octets can express a maximum value of about 34 gigabits. add snmp usm user test security-level authNoPriv auth-pass-phrase Vpn12345 authentication-protocol MD5. If that assumption is correct, there are a couple OIDs to investigate: 1.3.6.1.2.1.2.2.1.10 - ifInOctets returns the total number of octets received on the interface, including framing characters. When you say "interface utilisation", I assume you mean Ethernet interface utilization. Hi Lee, The OID you are referring to is for "ifHCInOctets" object in "IF-MIB". Instead of ifInOctets and ifOutOctets, query ifHCInOctets and ifHCOutOctets. Object ID 1.3.6.1.2.1.31.1.1.1.6 : Label iso.org.dod.internet.mgmt.mib-2.ifMIB.ifMI BObjects.ifXTable.ifXEntry.ifHCInOctets : Type 64bit Counter : Access Read Only : Description The total number of octets received on the interface, including framing characters. In SNMP tree, these will have different traffic counters present: ifInOctets and ifHCInOctets. 1. That's great, and it works, but we have another concern. I'm working under SNMP to get incoming traffic and outbound traffic, but I only have the OID of the incoming traffic, I could help with the OID of the outbound traffic, what I want to get is similar to the following graph. These are standard counters that should certainly be available on the high speed interfaces of the 6500/7600. As per RFC 2665, the four OID's (ifInOctets, ifOutOctets, ifHCInOctets, and ifHCOutOctets) should be adding the framing characters for the interface. With 64 bits, you can up to 18 446 744 073 709 552 000 octets (approximately 18,4 To). My reason for asking is because ifIn/OutOctets are counters, so what you will get when querying them is an average of bytes sent on that interface since your last poll, which will vary alot if the sampling intervals are not the same. This object is a 64-bit version of ifInOctets. ifHCInOctets. Created on 01-04-2010 11:18 AM. zabbix snmpzabbixsnmp. I have been using ifinoctets*8 and ifoutoctets*8 in the expressions respectively. For the SG-1100, I know its an Arm box, it one of the reasons I bought it. Hi, I have a question with regards to Red Hat Enterprise Linux 4 AS Update 2. Mar 6, 2019 at 11:58.
