Monitoring plugin to check network interfaces on Linux OS

check_netio's Issues

pnp4nagios

Hello,

I am looking for php4nagios plugin for this script?

Large performance data output is cut when using NRPE

When the plugin is executed locally, the full output is shown.
But when using NRPE as remote plugin executor, the output is cut:

$ /usr/lib/nagios/plugins/check_nrpe -H 10.10.1.106 -c check_netio -a "ens3"
NETIO OK - ens3: Receive 71037216695 Bytes, Transmit 98260284130 Bytes|NET_ens3_RX=71037216695B;;;; NET_ens3_TX=98260284130B;;;; NET_ens3_ERR_RX=0;;;; NET_ens3_ERR_TX=0;;;; NET_ens3_DROP_RX=0;;;; NET_ens3_DROP_TX=0;;;; SyncookiesSent=36;;;; SyncookiesRecv=36;;;; SyncookiesFailed=0;;;; EmbryonicRsts=23357;;;; PruneCalled=53;;;; RcvPruned=0;;;; OfoPruned=0;;;; OutOfWindowIcmps=6;;;; LockDroppedIcmps=0;;;; ArpFilter=0;;;; TW=11751533;;;; TWRecycled=0;;;; TWKilled=0;;;; PAWSPassive=0;;;; PAWSActive=0;;;; PAWSEstab=5;;;; DelayedACKs=4436739;;;; DelayedACKLocked=5264;;;; DelayedACKLost=21269;;;; ListenOverflows=4;;;; ListenDrops=1353;;;; TCPPrequeued=11034017;;;; TCPDirectCopyFromBacklog=3130294;;;; TCPDirectCopyFromPrequeue=47926137;;;; TCPPrequeueDropped=0;;;; TCPHPHits=15298970;;;; TCPHPHitsToUser=508;;;; TCPPureAcks=54508534;;;; TCPHPAcks=734055;;;; TCPRenoRecovery=19;;;; TCPSackRecovery=609;;;; TCPSACKReneging=0;;;; TCPFACKReorder=0;;;; TCPSACKReorder=0;;;; TCPRenoReorder=0;;;; TCPTSReorder=7;;;; TCPFullUndo=

This results in broken performance data. Icinga 2 logs it like this:

[2020-09-04 13:15:59 +0200] warning/InfluxdbWriter: Ignoring invalid perfdata for checkable '10.10.1.106!Network IO ens3' and command 'nrpe' with value: TCPFullUndo=
        (0) Processing check result for 'onl-lb01-dr!Network IO ens3'

[Question] Register TCP connection aborts with this?

Hi Claudio,
I just got a question and I cannot find another way to ask you.
Is it possible to register tcp connection aborts and reconnects with this plugin?
I have to check, if connections from one network to another are stable or have aborts after a couple of time.

Thanks and have a nice weekend,
Marcus

Errors without "-t" / $TCPSTATS undefined

# ./check_netio.sh -i eth0

Just add a default

TCPSTATS=false

FR: Add interface errors

Feature request: Add interface errors. First of all in performance data. But also add the possibility to to use thresholds.

Make sure ifconfig command exists

Plugin doesn't fail (still returns OK) when ifconfig is not installed and simply returns empty values.
