Measurement
Unit |
Interpretation |
| Avg_pkts_rate |
Refers to the
average time (in seconds) used by the DHCP server to process each
packet it receives |
Pkts/sec |
This measure can
vary depending on the server hardware and its I/O subsystem.
A sudden or unusual increase might indicate a problem, either due
to the I/O subsystem becoming slower or because of an intrinsic
processing overhead on the server computer. |
| Curr_msg_queue_len: |
Refers to the
current length of the internal message queue of the DHCP server |
Number
|
A large value in
this measure might indicate heavy server traffic. |
| Req_rate |
Refers to the
number of DHCP request messages received per second by the DHCP server
from clients |
Reqs/sec
|
A sudden or
unusual increase in this measure indicates that a large number of
clients are trying to renew their leases with the DHCP server. |
| Req_acks_rate |
Refers to the
number of DHCP acknowledgement messages sent per second by the DHCP
server to clients |
Reqs/sec
|
A sudden or
unusual increase in this measure indicates that a large number of
clients are being renewed by the DHCP server. |
| Req_nacks_rate |
Refers to the
number of negative acknowledgement messages sent per second by the
DHCP server to clients |
Reqs/sec
|
A very high value
might indicate potential network trouble in the form of
misconfiguration of either the server or clients.
When servers are misconfigured, one possible cause is a deactivated
scope.
For clients, a very high value could be caused by computers moving
between subnets, such as laptop portables or other mobile devices. |
| Req_declines_rate |
Refers to the
number of DHCP decline messages received per second by the DHCP server
from clients |
Reqs/sec
|
A high value
indicates that several clients have found their address to be in
conflict, possibly indicating network trouble. |
| Pkts_exprd_rate |
Refers to the
number of packets per second that expire and are dropped by the DHCP
server |
Pkts/sec
|
A large value in
this measure indicates that the server is either taking too long to
process some packets while other packets are queued and becoming
stale, or traffic on the network is too high for the server to manage. |
| Pkts_drop_rate |
Refers to the
number of duplicate packets per second dropped by the DHCP server |
Pkts/sec
|
This measure can
be affected by multiple clients or network interfaces forwarding the
same packet to the server.
A large value in this measure indicates that either clients are
probably timing out too fast or the server is not responding fast
enough. |
| Req_release_rate |
Refers to the
number of DHCP release messages received per second by the DHCP server
from clients |
Reqs/sec
|
This measure only
exists if a DHCP client sends a release message to the server. This
measure remains low for many DHCP network configurations. |
