NimbostratusHeat Maps irule by Colin.
Hi,
Thanks to Colin Walker for the great heatmap's irule.
I have tried to implement this irule but run into some problems and not sure where to look..Below is what I see in the l...

NimbostratusSorry I hope the below works.
when RULE_INIT {
Configure static portions of the HTML response for the heatmap pages
set static::resp1 "
Table Cleared.
"
}
default {
Look up country & state locations
set cloc [whereis [IP::client_addr] country]
set sloc [whereis [IP::client_addr] abbrev]
If the IP doesn't resolve to anything, pick a random IP (useful for testing on private networks)
if {($cloc eq "") and ($sloc eq "")} {
set ip [expr { int(rand()*255) }].[expr { int(rand()*255) }].[expr { int(rand()*255) }].[expr { int(rand()*255) }]
set cloc [whereis $ip country]
set sloc [whereis $ip abbrev]
if {($cloc eq "") or ($sloc eq "")} {
set cloc "US"
set sloc "WA"
}
}
Strip slashes from URI to allow easy queries
set friendlyURL [string map {/ ""} [HTTP::uri]]
Create a new table named country:location or state:location
set cloc "country:$cloc"
if {[table incr -subtable $cloc -mustexist $friendlyURL] eq ""} {
table set -subtable country:$cloc $friendlyURL 1 indefinite indefinite
}
Update the mytables pointer table with the new country or state table name
if {[table incr -subtable mytables -mustexist country:$cloc] eq ""} {
table set -subtable mytables country:$cloc 1 indefinite indefinite
}
Same as above for states, not countries.
if {$cloc eq "US"} {
if {[table incr -subtable state:$sloc -mustexist $friendlyURL] eq ""} {
table set -subtable state:$sloc $friendlyURL 1 indefinite indefinite
}
if {[table incr -subtable mytables -mustexist state:$sloc] eq ""} {
table set -subtable mytables state:$sloc 1 indefinite indefinite
}
}
HTTP::respond 200 Content "Added - Country: $cloc State: $sloc"
}
}
} Here is your site's usage:\
Connections per Region:
"
set static::resp2 "
Zoom to region:\
| | | | \
| | "
set static::resp4 ""
}
when HTTP_REQUEST timing on {
switch -glob [string tolower [HTTP::uri]] {
"/asia*" -
"/africa*" -

"/usa*" -
"/world*" -
"/heatmap*" {
set chld ""
set chd ""
set zoom ""
set zoomURL ""
set regions ""
set urlTotal 0
set regionTotal 0
Split apart the zoom region from the filter URL in the request
set zoom [getfield [string map {"/" "" "heatmap" "world"} [HTTP::uri]] "?" 1]
set zoomURL [getfield [string map {"/" "" "heatmap" "world"} [HTTP::uri]] "?" 2]
Get a list of all states or countries, applying the URL filter where necessary
and retrieve the associated count of requests from that area to that URL
First step through the mytables table, which is a pointer table referencing all subtables with counter values in them
foreach mysub [table keys -subtable mytables] {
Next determine whether to search state or country tables
if {$zoom eq "usa"} {
if {$mysub starts_with "state:"} {
For each state sub table step through each key, which will be a URL, and count the request to that URL.
This is also where URL filtering is applied if applicable
foreach myurl [table keys -subtable $mysub] {
if {$zoomURL ne ""} {
if {$myurl eq $zoomURL} {
append chld "[getfield $mysub ":" 2]"
append chd "[table lookup -subtable $mysub $myurl],"
set urlTotal [table lookup -subtable $mysub $myurl]
}
} else {
append chld "[getfield $mysub ":" 2]"
append chd "[table lookup -subtable $mysub $myurl],"
set urlTotal [table lookup -subtable $mysub $myurl]
}
set regionTotal {expr $regionTotal + $urlTotal}
set urlTotal 0
}
append regions "[getfield $mysub ":" 2] : $regionTotal"
set regionTotal 0
}
} else {
if {$mysub starts_with "country:"} {
foreach myurl [table keys -subtable $mysub] {
if {$zoomURL ne ""} {
if {$myurl eq $zoomURL} {
append chld "[getfield $mysub ":" 2]"
append chd "[table lookup -subtable $mysub $myurl],"
set urlTotal [table lookup -subtable $mysub $myurl]
}
set regionTotal {expr $regionTotal + $urlTotal}
set urlTotal 0
} else {
append chld "[getfield $mysub ":" 2]"
append chd "[table lookup -subtable $mysub $myurl],"
set urlTotal [table lookup -subtable $mysub $myurl]
}
set regionTotal {expr $regionTotal + $urlTotal}
set urlTotal 0
}
append regions "[getfield $mysub ":" 2] : $regionTotal"
set regionTotal 0
}
}
}
Send back the pre-formatted response, set in RULE_INIT, combined with the map zoom, list of areas, and request count
set chd [string trimright $chd ","]
First loop through the trackingurls class to get a list of all URLs to be tracked and format HTML around them for links
set filters ""
foreach mytrackingurl class names trackingurls {
append filters " | "
}
set filters [string trimright $filters " | "]
Combine the above generated HTML with the static HTML in RULE INIT and respond to the client
HTTP::respond 200 content "${static::resp1}${regions}${static::resp2}${zoom}&chd=t:${chd}&chld=${chld}${static::resp3} \
