#StackBounty: #amazon-ec2 #dhcp #log-files #rsyslog Interpreting DHCP related message from rsyslog

Bounty: 50

In /var/log/messages from an EC2 instance there are a lot of lines such as:

<date/timestamp> ip-<IP_HERE> ec2net: [get_meta] Trying to get http://169.254.169.254/latest/meta-data/network/interfaces/macs/MAC_ADDR/local-ipv4s
<date/timestamp> ip-<IP_HERE> ec2net: [rewrite_aliases] Rewriting aliases of eth0
<date/timestamp> ip-<IP_HERE> dhclient[2187]: XMT: Solicit on eth0, interval 112321ms.
<date/timestamp> ip-<IP_HERE> dhclient[2187]: XMT: Solicit on eth0, interval 111231ms.
....
and more XMT: Solicit messages (hundreds more)

Why would there be hundreds of these solicit messages, and what does XMT: Solicit on eth0mean? How should I interpret this?

Is this simply the log of a DHCP request (or many requests)? I haven’t seen “XMT” previously.
