# check_snmp_interface
This script is intended to be an icinga, nagios or naemon plugin which measures the network traffic of one or more network interfaces via SNMP.

The php script is needed by pnp4nagios and is made for one network interface.

# Usage
First of all, don't run this script as root. It will create a temporary file called /tmp/<hostname>_check_snmp_interface___IF__.gap, with the actual measures. Where _IF_ gets replaced by the network interface name. The script comes with a help option.

```
$ ./check_snmp_interface -h
check_snmp_interface 0.0.4

GNU v2 or later, see <http://www.fsf.org/copyleft/gpl.txt>

# Example

Measure the network traffic of eth0 on localhost. Only Inbound and outbound traffic is needed.

```
$ ./check_snmp_interface -H localhost -C mycommunity -i eth0
Network Interface OK - eth0 Outbound=408.96Bps  Inbound=161.42Bps  | 'eth0_ifoutoctets'=408.96Bps;;;0;125000000 'eth0_ifinoctets'=161.42Bps;;;0;125000000
```

Lets show the output in the status as percent.

```
$ ./check_snmp_interface -H localhost -C mycommunity -i eth0 -u %
Network Interface OK - eth0 Outbound=0.00%  Inbound=0.00%  | 'eth0_ifoutoctets'=77.16Bps;;;0;125000000 'eth0_ifinoctets'=110.58Bps;;;0;125000000
```

Add some thresholds for in- and outbound traffic in percent.

```
$ ./check_snmp_interface -H localhost -C mycommunity -i eth0 -u % -w 80,80 -c 90,90
Network Interface OK - eth0 Outbound=0.00%  Inbound=0.00%  | 'eth0_ifoutoctets'=8.71Bps;100000000.00;112500000.00;0;125000000 'eth0_ifinoctets'=15.95Bps;100000000.00;112500000.00;0;125000000
```

Show me also the operation status flag of the interface and alarm me if it is differen as expected.

```
$ ./check_snmp_interface -H localhost -C mycommunity -i eth0 -u % -w 80,80 -c 90,90 -O down
Network Interface OK - eth0 O=up Outbound=0.00% Inbound=0.00% | 'eth0_ifoutoctets'=31.64Bps;100000000.00;112500000.00;0;125000000 'eth0_ifinoctets'=50.76Bps;100000000.00;112500000.00;0;125000000
```

Show me all available information and flags but do not alarm me for thrueput.

```
./check_snmp_interface -H localhost -C mycommunity -i eth0 -u bps -s ifoutoctets,ifinoctets,ifoutdiscards,ifindiscards,ifouterrors,ifinerrors -w none,none,none,none,none,none -c none,none,none,none,none,none -A up -O up -P off
Network Interface OK - eth0 A=up O=up P=off Outbound=1805.89bps Inbound=2024.84bps | 'eth0_ifoutoctets'=225.74Bps;;;0;125000000 'eth0_ifinoctets'=253.11Bps;;;0;125000000 'eth0_ifoutdiscards'=0.00Pkts;; 'eth0_ifindiscards'=0.00Pkts;; 'eth0_ifouterrors'=0.00Pkts;; 'eth0_ifinerrors'=0.00Pkts;;
```

Show me the output of all interfaces

```
$ ./check_snmp_interface -H localhost -C mycommunity
Network Interface OK - eth0 Outbound=83.33Bps  Inbound=34.65Bps lo Outbound=0.00Bps  Inbound=0.00Bps xif1 Outbound=786.28Bps  Inbound=649.06Bps xif2 Outbound=140.48Bps  Inbound=185.21Bps xif3 Outbound=132.67Bps  Inbound=177.64Bps xif4 Outbound=0.00Bps  Inbound=0.00Bps xif5 Outbound=0.00Bps  Inbound=0.00Bps  | 'eth0_ifoutoctets'=83.33Bps;;;0;125000000 'eth0_ifinoctets'=34.65Bps;;;0;125000000 'lo_ifoutoctets'=0.00Bps;;;0;1250000 'lo_ifinoctets'=0.00Bps;;;0;1250000 'xif1_ifoutoctets'=786.28Bps;;;0;0 'xif1_ifinoctets'=649.06Bps;;;0;0 'xif2_ifoutoctets'=140.48Bps;;;0;0 'xif2_ifinoctets'=185.21Bps;;;0;0 'xif3_ifoutoctets'=132.67Bps;;;0;0 'xif3_ifinoctets'=177.64Bps;;;0;0 'xif4_ifoutoctets'=0.00Bps;;;0;0 'xif4_ifinoctets'=0.00Bps;;;0;0 'xif5_ifoutoctets'=0.00Bps;;;0;0 'xif5_ifinoctets'=0.00Bps;;;0;0
```

Show me the output for virtual interfaces only

```
$ ./check_snmp_interface -H localhost -C mycommunity -i xif -r
Network Interface OK - xif1 Outbound=687.67Bps  Inbound=528.74Bps xif2 Outbound=178.08Bps  Inbound=209.15Bps xif3 Outbound=149.46Bps  Inbound=192.52Bps xif4 Outbound=0.89Bps  Inbound=0.71Bps xif5 Outbound=0.89Bps  Inbound=0.71Bps  | 'xif1_ifoutoctets'=687.67Bps;;;0;0 'xif1_ifinoctets'=528.74Bps;;;0;0 'xif2_ifoutoctets'=178.08Bps;;;0;0 'xif2_ifinoctets'=209.15Bps;;;0;0 'xif3_ifoutoctets'=149.46Bps;;;0;0 'xif3_ifinoctets'=192.52Bps;;;0;0 'xif4_ifoutoctets'=0.89Bps;;;0;0 'xif4_ifinoctets'=0.71Bps;;;0;0 'xif5_ifoutoctets'=0.89Bps;;;0;0 'xif5_ifinoctets'=0.71Bps;;;0;0
```
