Casual Log Collection and Querying with fluent-plugin-riak @kuenishi from @basho
2013/6/1 RubyKaigi
Who the hell are you? •UENISHI, Kota (@kuenishi) •Basho Japan
KK •devoted to Distributed Systems for ~6 yrs •msgpack-erlang, Jubatus
Casual Log Collection •Aggregate Every Log with Fluentd •Put Them
all into <Some Storage You Like> •Ask your Query to <Some Storage You Like>
Whole Sketch
fluentd: casual log collector http://www.flickr.com/photos/markchadwick/8757802771/ http://www.flickr.com/photos/usdagov/5681152426/ before: logs are scattered
all over the servers in chaos after: all logs flows cleanly via fluentd in order

Frontend Access logs syslogd App logs System logs Backend Databases

Nagios MongoDB Hadoop Alerting Amazon S3 Analysis Archiving MySQL Apache

what’s ? •Distributed Key-Value Store •Focused on •Availability •Scalability •Easy
Operation, ҆ (Sleep)
when Riak? •Hadoop is too much •MongoDB is too small
•Document DB aspect of Riak •put them all into Riak
Not Only KVS •Aspect of Document Database •MapReduce in JavaScript
/ Erlang
Buy it if interested
fluent-plugin-riak JSON
fluent.conf <match apache.**> type riak # define the cluster via
pb ports nodes 192.168.0.1:8087 192.168.0.2:8087 </match>
log everything as JSON { "host":"103.5.142.5", "user":"-", "method":"PUT", "path":"/buckets/moriyoshi/object/riaklogo.png", "code":"200",
"size":"0", "referer":"", "agent":"", "time":"2013-05-27T05:42:09Z", "tag":"riak.cluster2" }, ...
How to Query
Ruby Cluent for Querying irb> q = client.bucket(‘fluentlog’) irb> q
= q.map(“function(v){ return [v]; }”).reduce(“function(values){ return values; }“, :keep => false) irb> r = q.run()
Debug distributed JS http://www.flickr.com/photos/heatsink/110859301/
Any Other Rubyish way? http://www.flickr.com/photos/snazzyshot/5366645175/
ripple

Mohair: Not Only NoSQL http://www.flickr.com/photos/frank-wouters/2464743512/
JSON { "host":"103.5.142.5", "user":"-", "method":"PUT", "path":"/buckets/moriyoshi/object/riaklogo.png", "code":"200", "size":"0", "referer":"", "agent":"",
"time":"2013-05-27T05:42:09Z", "tag":"riak.cluster2" }, ...
SQL create table apachelogs { host varchar(16), user varchar(256), method
varchar(5), path varchar(1024), code integer, size integer, referer text, agent varchar(1024), time timestamp, tag varchar(1024) }
“Mohair” for Querying > select * from fluentlog \ where
method = “GET” group by host
Converting SQL to MapReduce •SQL -(parslet)-> JS -> Riak mapred
•where sentence is at Map •group by, count(-) is at Reduce
Chef’s Capricious Roadmap •Secondary Index Support •Query Optimization •types: timestamp,
float •nested columns •insert / delete
check it out! github: basho/riak kuenishi/fluent-plugin-riak kuenishi/mohair (kuenishi/fluent-logger-erlang)
Conclusion •NoSQL is not NoSQL any more •put’em all into
Riak via Fluentd •Query via SQL with Mohair •waiting for pull requests
