A few bad redirects on logstash.net

[jordansissel]

The following are redirecting to elastic.co (correctly) but are directing users to pages that are missing.

These should be easy to fix, but here's the list:

/docs/VERSION/
/docs/VERSION/filters/advisor
/docs/VERSION/filters/grep
/docs/VERSION/filters/grok
/docs/VERSION/filters/grokdiscovery
/docs/VERSION/filters/noop
/docs/VERSION/filters/useragent
/docs/VERSION/flags
/docs/VERSION/inputs/collectd
/docs/VERSION/inputs/gemfire
/docs/VERSION/inputs/s3
/docs/VERSION/outputs/amqp
/docs/VERSION/outputs/elasticsearch
/docs/VERSION/outputs/elasticsearch.html
/docs/VERSION/outputs/elasticsearch_http
/docs/VERSION/outputs/file
/docs/VERSION/outputs/s3
/docs/VERSION/release-notes

With thanks to @russorat for pointing me at the right place to find this data! <3

@sylvie777 poked me about these today; I'll see if I can't clean them up on the logstash.net side of things first, so hopefully, we won't need to make changes to anything on elastic.co

@jordansissel Thanks, Jordan! If I can help (e.g., test links), please let me know. Happy to help. :)

Also these pages are 404 on logstash.net and should redirect to appropriate places on elastic.co:

/docs/1.5.0/extending/example-add-a-new-filter
/docs/1.5.0/getting-started-centralized
/docs/1.5.0/extending/
/docs/1.5.0/release-notes
/docs/1.5.0/tutorials/metrics-from-logs
/docs/1.5.0/life-of-an-event
/docs/1.5.0/installation
/docs/1.5.0/tutorials/getting-started-simple
/docs/1.5.0/contrib-plugins

/docs/1.5.0/tutorials/10-minute-walkthrough/
/docs/1.5.0/configuration
/docs/1.5.0/tutorials/getting-started-with-logstash

Most common links from within logstash.net to 404s against pages missing in 1.5.0:

% grep '" 404 [0-9]' other_vhosts_access.log | fex '"2 2' '"4' | grep '^/docs/1.5.0' | sort | uniq -c | sort -n | awk '$1 > 50'
     53 /docs/1.5.0/release-notes http://www.logstash.net/docs/1.4.2/release-notes

I'll use these as a basis for updating the 404 routing on logstash.net's 404 page

[jordansissel]

Here's a few samples of improved redirects. The specific redirects and recommendations improvements can be seen in the javascript here: logstash/logstash.net@6af9f35#diff-eaf2b86188ec63e62e4c3e71eb198df1R24

I'll deploy this tomorrow once I test a bit more.

[jordansissel]

I fixed up a few other links I forgot to add in my first pass. Things are looking pretty solid now when I test locally.

I'll deploy to logstash.net tomorrow unless I need to wait; @russorat and @sylvie777; thoughts?

[sylvie777]

@jordansissel Cool! I don't have anything holding back the deployment on my end.
