Update:

After adding more instrumentation, including Apache2 processes, Apache2 CPU and a questionable MySQL CPU graph, the first spike of the last half day occurred and there is correlation between the load spikes and sudden increase in Apache2 processes:

But is is not clear what the cause is since there is no strong correlation to users, guests or bot activity. But there is some potential correlation to bot activity:

Which brings me back, full circle, suspecting rogue bot activity, again.... let's see what happens during the next spike.

NAME
Apache2::ConnectionUtil - Perl API for Apache connection utils Synopsis use Apache2::Connection (); use Apache2::ConnectionUtil (); use Apache2::RequestRec (); # grab the connection object; my $c = $r->connection; # share perl objects like $r->pnotes $old_val = $c->pnotes($key => $value); Description "Apache2::ConnectionUtil" provides the Apache connection record object utilities API. API
"Apache2::ConnectionUtil" provides the following functions and/or methods: "pnotes" Share Perl variables between requests over the lifetime of the connection. $old_val = $c->pnotes($key => $val); $val = $c->pnotes($key); $hash_ref = $c->pnotes(); obj: $c ( "Apache2::Connection object" ) opt arg1: $key ( string ) A key value opt arg2: $val ( SCALAR ) Any scalar value (e.g. a reference to an array) ret: (3 different possible values) if both, $key and $val are passed the previous value for $key is returned if such existed, otherwise undef is returned. if only $key is passed, the current value for the given key is returned. if no arguments are passed, a hash reference is returned, which can then be directly accessed without going through the "pnotes()" interface. since: 2.0.3 See ("Apache2::RequestUtil::pnotes") for the details of the "pnotes" method usage. The usage is identical except for a few differences. First is the use of $c instead of $r as the invocant. The second is that the the data persists for the lifetime of the connection instead of the lifetime of the request. If the connection is lost, so is the data stored in "pnotes".
