Now it's just a matter of using which one of those. ifinoctets, ifoutoctets - interface utilization grafana vs prtg reports Ivan Azzopardi <ivanazzopardi@.> #1557 . In SNMP tree, these will have different traffic counters present: ifInOctets and ifHCInOctets. multiply by 8 to get bits/s Do you have other SNMP devices to compare with? Even with a 100% utilized 100Gb/s interface, you'll still only roll over a counter every 5.8 years or so. 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. Basic WAN optimization topology. 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. This object is a 64-bit version of ifInOctets. Port ethernet2/2: 10GigabitEthernet2/2 (22 / #3210) ifHCInOctets ifHCOutOctets ifHCInUcastPkts ifHCOutUcastPkts ifHCInBroadcastPkts ifHCOutBroadcastPkts ifHCInMulticastPkts ifHCOutMulticastPkts ifHighSpeed dot3Duplex VLAN == 1Using ifDescr as ifAlias10GigabitEthernet2/2 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). Distributing WAN optimization processing. 1.3.6.1.2.1.2.2.1.16 - ifOutOctets returns the total number . 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 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. Explicit web proxy topologies. 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. 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 This object is a 64-bit version of ifInOctets. NetCrunch Datasource - ifInOctets to bytes/sec? These 64 bit counters are already defined in the OpenNMS data collection config, and in fact are probably being collected right under your nose. Example topologies. 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. Out-of-path WAN optimization topology. For example: SNMP does not return any Counter64 values for any of my OpenVPN interfaces (client or server). 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. 1 Answer Sorted by: 1 Difference is the maximal value can be set between 2^32 and 2^64. During initial installation, it asks whether we want to install netsnmp or not. Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site 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. ifInOctets is expressed as 32-bit unsigned integer. 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. out: . Where did you pull the value from? This object is a 64-bit version of ifInOctets. "The total number of octets received on the interface,including framing characters. They are 64 bit counters, and only roll over once every 18 exabytes. But anyway, that difference looks weird. The problem I'm having is that on my networking devices, the snmp data is being sent over in octets instead of bits/bytes. This results into empty traffic graphs in our monitoring solution. I said arm64, as that's what bsnmpd reported, instead of Aarch64. Disk usage. At 100 Mbps, the minimum wrap time is 5.7 minutes, and at 1 Gbps, the minimum is 34 seconds. 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. I'd say you shouldn't run over whole tree of SNMP OIDs, it takes a significant amount of time. I've tested a few times by using snmpwalk | grep InOctets and subtracting the values. Ie not using ifHCinoctets in grafana backend and ifinoctets in prtg, or other way around. ifHCInOctets. 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 . I can get Mbs for any collected datapoint time by: taking it as it is, bytes/s. Every Second, an interface will count the octets (bytes) going in and out and will present them as either ifinoctets or ifoutoctets. 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. Counter64 (SNMPv2-SMI) Module. Your hunch is correct - you want the 64-bit mib-2 counters ifHCInOctets and ifHCOutOctets. FortiGate models that support WAN optimization. These are standard counters that should certainly be available on the high speed interfaces of the 6500/7600. set snmp usm user test vsid all. add snmp usm user test security-level authNoPriv auth-pass-phrase Vpn12345 authentication-protocol MD5. Discontinuities in the value of this counter can occur at re-initialization of the . This object is a 64-bit version of ifInOctets. However, in Juniper's implementation, the traffic statistics that are retrieved via SNMP do not include the 14 byte Ethernet header overhead. I am trying to replicate a Bandwidth in / Bandwidth Out / Bandwidth in+out sum, report from prtg with grafana v2.6.0. The IF-MIB SNMP MIB defines the generic objects for network interface sub-layers. snmpwalk -v 3 -u test -a MD5 -A Vpn12345 -n ctxname_vsid3 -l authNoPriv localhost IF-MIB::ifInOctets. 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. zabbix snmpzabbixsnmp. Hey there, I'm new to grafana, and have installed the netcrunch app to link into our netcrunch data. For example, a 10 Mbps stream of back-to-back, full-size packets causes ifInOctets to wrap in just over 57 minutes. Instead of ifInOctets and ifOutOctets, query ifHCInOctets and ifHCOutOctets. As per RFC 2665, the four OID's (ifInOctets, ifOutOctets, ifHCInOctets, and ifHCOutOctets) should be adding the framing characters for the interface. IPHost Network monitor uses SNMP for monitoring health and availability of devices and applications in your network. Sushil Kumar Katre. The only interfaces with 64-bit counters are the two NICs and their VLANs. Logging Settings on the device send these out and Zabbix holds on to intervals, in our case 5 mins. Created on 01-04-2010 11:18 AM. 2 32 = 4,294,967,296. But anyway, that difference looks weird. WAN optimization with web caching. I am trying to check interface receive/send counters using snmp. Back to rfc1573 MIB page. Zero touch, Kickstart, Monitoring, Web scraping, Headless setup &amp; Low power device When you say "interface utilisation", I assume you mean Ethernet interface utilization. IF-MIB (Force10-9.14.2.1) Nom. 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. elleryweber August 31, 2017, 3:53pm #1. Valued Contributor. Requiring that interfaces be polled frequently enough not to miss a counter wrap is increasingly problematic. Do you have other SNMP devices to compare with? In the RFC1213-MIB it describes the values as octets received and sent on the interface, but not under which time interval. There's a similar case to be made for e.g. For interfaces that operate at 20,000,000 (20 million) bits per second or less, you must use 32-bit byte and packet counters. Please support me on Patreon: https://www.patreon.com/roelvandepaarWith th. 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. I have been using ifinoctets*8 and ifoutoctets*8 in the expressions respectively. 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. Especially CPEs and ToR switches tend to do these things on really, really slow userspace CPUs. 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. 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 max value for the 64-bit counters is also ~4GB. Rising star. 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. The IF-MIB values that are returned for this IAP for ifInOctects and ifOutOctets are zero. 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. 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 the differences in values returned by ifInOctets/ifOutOctets and ifHCInOctets/ifHCOutOctets aren't always identical. 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. 11-02-2008 07:18 PM. 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? And then the trick is to use correct context naming ctxname_vsid<nbr>. the discrepancy in the report . Grafana. For example on VS3. . Acces. The high-capacity nterface counters (ifHC*Octets) should never be collected from a node that is using SNMPv1. Everything is good, except that I ju. ifInOctets OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The total number of octets received on the interface, including framing characters." ::= { ifEntry 10 } See also the OID Repository website reference for 1.3.6.1.2.1.2.2.1.10 With 32 bits, you can up to 4 294 967 295 octets (approximately 4.2 Go). I'm trying to graph network usage on my router for a specific interface using data from SNMP. Hi Lee, The OID you are referring to is for "ifHCInOctets" object in "IF-MIB". ifHCInOctets.1,IF-MIB::ifHCInOctets.2, what does these number 1,2 represent here. 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. - amit singh. 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 the differences in value Syntaxe. For the SG-1100, I know its an Arm box, it one of the reasons I bought it. New Behavior 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. version of ifInOctets. DevOps & SysAdmins: SNMP differences in ifInOctets vs ifHCInOctets valuesHelpful? IF-MIB::ifInOctets.2 = Counter32: 205536488. Options. IfInOctets=0, IfOutOctets=0 for Aruba IAP Version 6.4.2.0-4.1.1.1. a 32 bit counter will wrap decreases. Hi, I have a question with regards to Red Hat Enterprise Linux 4 AS Update 2. 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}". IF-MIB::ifInOctets.1 = Counter32: 3195699413. Thanks for taking the time to read this post, my query is as follows. Description by oid_info ifHCInOctets OBJECT-TYPE SYNTAX Counter64 MAX-ACCESS read-only STATUS current DESCRIPTION Did you once have these This is SNMP basics, it's a reference to the interface table in which all interfaces are listed. Before transfer: # snmpwalk -v2c -c public greco | grep 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. IF-MIB::ifInOctets.2 = Counter32: 0. As a demonstration, I'll transfer a 1 gigabyte file from a physical host to an ESXi guest (using vmnic2, watch the third counter). - IfInOctets: "The total number of octets received on the interface, including framing characters. Options. Following is the description for the same -. Ie not using ifHCinoctets in grafana backend and ifinoctets in prtg, or other way around. 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 Note: The SNMP counters wrap, the command line interface (CLI) counters do not. ifInOctets / ifOutOctets32graphicsifInOctets / ifOutOctetsifHCInOctets / ifHCOutOctets snmpwalk | grep InOctetstesting snmpwalk | grep InOctets 32 .
