RX packets dropped ratio too high-f5-all
Vendor: f5
OS: all
Description:
Indeni tracks the number of packets that had issues and alerts if the ratio is too high.
Remediation Steps:
Packet drops usually occur when the rate of packets received is higher than the device’s ability to handle.
How does this work?
This alert logs into the F5 unit through the F5 iControl REST API and retrieves the metrics from all network interfaces. In that output, it looks for the number of packets dropped on an interface.
Why is this important?
If incoming packets are being dropped on a network interface, it is important to be aware of it. This may be due to a high load on the unit, or another capacity issue.
Without Indeni how would you find this?
An administrator could login to the web interface of the device and go to Network -> Interfaces -> Statistics to see the statistics of each interface. This information is also available by logging into the device through SSH, entering TMSH and executing the command “show net interface all-properties”.

network-interface-state:
why: |
Interfaces in the "down" state could result in downtime or reduced redundancy.
how: |
The state of the interface is retrieved via the F5 iControl REST API.
can-with-snmp: true
can-with-syslog: false
network-interface-admin-state:
why: |
An administrator might set a network interface to be disabled for troubleshooting, but. Should he he forget about doing this network trunks might be running at reduced capacity.
how: |
This alert uses the F5 iControl REST API to retrieve the status of all physical network interfaces. In that output, it looks for interfaces that are set to be up, but are actually down.
can-with-snmp: true
can-with-syslog: false
network-interface-mac:
why: |
To be able to search for MAC addresses in indeni, this data needs to be stored.
how: |
This alert uses the F5 iControl REST API to retrieve the MAC addresses of all physical network interfaces.
can-with-snmp: true
can-with-syslog: false
network-interface-mtu:
why: |
The MTU sometimes needs to be adjusted. Storing this gives an administrator an easy way to view the MTU from a large number of devices, as well as identifying incorrectly set MTU.
how: |
This alert uses the F5 iControl REST API to retrieve the MTU from all physical interfaces.
can-with-snmp: true
can-with-syslog: false
network-interface-rx-packets:
why: |
Tracking the number of packets flowing through each network interface is important to identify potential issues, spikes in traffic, etc.
how: |
This alert logs into the F5 unit through the F5 iControl REST API and retrieves the metrics from all network interfaces. In that output, it looks for the number of packets received through the interface.
can-with-snmp: true
can-with-syslog: false
network-interface-tx-packets:
why: |
Tracking the number of packets flowing through each VLAN interface is important to identify potential issues, spikes in traffic, etc.
how: |
This alert logs into the F5 unit through the F5 iControl REST API and retrieves the metrics from all network interfaces. In that output, it looks for the number of packets transmitted through the interface.
can-with-snmp: true
can-with-syslog: false
network-interface-rx-dropped:
why: |
If incoming packets are being dropped on a network interface, it is important to be aware of it. This may be due to a high load on the unit, or another capacity issue.
how: |
This alert logs into the F5 unit through the F5 iControl REST API and retrieves the metrics from all network interfaces. In that output, it looks for the number of packets dropped on an interface.
can-with-snmp: true
can-with-syslog: true
network-interface-tx-dropped:
why: |
If outgoing packets are being dropped on a network interface, it is important to be aware of it. This may be due to a high load on the unit, or another capacity issue.
how: |
This alert logs into the F5 unit through the F5 iControl REST API and retrieves the metrics from all network interfaces. In that output, it looks for the number of packets dropped on an interface.
can-with-snmp: true
can-with-syslog: false
network-interface-rx-bits:
why: |
Tracking the amount of data flowing through each network interface is important to identify potential issues, spikes in traffic, etc.
how: |
This alert logs into the F5 unit through the F5 iControl REST API and retrieves the metrics from all network interfaces. In that output, it looks for the number of bits received through the interface.
can-with-snmp: true
can-with-syslog: false
network-interface-tx-bits:
why: |
Tracking the amount of data flowing through each network interface is important to identify potential issues, spikes in traffic, etc.

can-with-snmp: true
can-with-syslog: false
network-interface-tx-errors:
why: |
Transmit errors on an interface could indicate a problem.
how: |
This alert logs into the F5 unit through the F5 iControl REST API and retrieves the metrics from all network interfaces. In that output, it looks for the number of transmit errors on each interface.
can-with-snmp: true
can-with-syslog: false
network-interface-rx-errors:
why: |
Receive errors on an interface could indicate a problem.
how: |
This alert logs into the F5 unit through the F5 iControl REST API and retrieves the metrics from all network interfaces. In that output, it looks for the number of receive errors on each interface.
can-with-snmp: true
can-with-syslog: false
network-interface-speed:
why: |
Generally, these days network interfaces are set at 1Gbps or more. Sometimes, due to a configuration or device issue, an interface can be set below that (to 100mbps or even 10mbps). As that is usually _not_ the intended behavior, it is important to track the speed of all network interfaces.
how: |
This alert logs into the F5 unit through the iControl REST API and retrieves the status of all network interfaces. In that output, it looks for the actual runtime speed of each interface.
can-with-snmp: true
can-with-syslog: false
network-interface-duplex:
why: |
Generally, these days network interfaces are set at full duplex. Sometimes, due to a configuration or device issue, an interface can be set to half duplex. As that is usually _not_ the intended behavior, it is important to track the duplex setting of all network interfaces.
how: |
This alert logs into the F5 unit through the iControl REST API and retrieves the status of all network interfaces. In that output, it looks for the actual runtime duplex of each interface.
can-with-snmp: true
can-with-syslog: false
network-interface-type:
why: |
The type of interface can be useful for administrators.
