Chapter 10. Monitoring & Statistics¶
This chapter will cover monitoring and statistics. While monitoring and statistics can be interpreted differently based on how they are used, they are similar in that they both use numbers to describe the system.
The most important feature is that it updates in real time. It is important to be able to view real-time status updates, and even a five-minute delay is too long. It is also important to know if the many policies are taking effect when they are applied. All statistics are collected every second.
Statistics are collected for each virtual host and are provided in real time (every second), with an average being provided every five minutes. The results are provided in JSON and XML formats for the users to analyze and process the results easily.

http://127.0.0.1:10040/monitoring/average?type=[JSON or XML]
realtimeDisplays the service status from one second ago.averageDisplays the average of five minutes of statistics.
Data Range¶
The range of data to be collected can be configured.
# server.xml - <Server><VHostDefault>
# vhosts.xml - <Vhosts><Vhost>
<Stats>
<DirDepth>0</DirDepth>
<DirDepthAccum>OFF</DirDepthAccum>
<HttpsTraffic>OFF</HttpsTraffic>
<ClientLocal>OFF</ClientLocal>
<OriginLocal>OFF</OriginLocal>
</Stats>
<DirDepth> (default: 0)Collects statistics for each directory. If set to zero, statistics will be collected in the root (/) directory. If set to one, statistics will be collected in directories one level down.
Note
Though there is no limit to the value that can be set, collecting statistics for too many directories can cause memory problems.
<DirDepthAccum>Configures whether or not to accumulate statistics in the parent directory when collecting the statistics for each directory. If
<DirDepth>is set to zero, this setting is ignored.OFF (default)Statistics are not accumulated in the parent directory.ONStatistics are accumulated in the parent directory.
For example, let’s assume that
<DirDepth>is set to two and all directories have ten lines of traffic. If<DirDepthAccum>is set toOFF, then statistics will be collected in each directory where traffic occurs, as shown in the left diagram. If set toON, statistics from lower directories are accumulated in parent directories, as shown in the right diagram.
Accumulated statistics in the parent directory.
In this example, the sum of the traffic in the /img directory and its subdirectories is 30, which is accumulated into the parent directory.
<HttpsTraffic>OFF (default)HTTPS traffic is only collected in SSL statistics.ONHTTPS traffic is collected into both SSL and HTTP statistics.
Generally, traffic that passes through the SSL layer is stored separately as SSL statistics. However, HTTPS will be processed as HTTP in upper protocols, so more detailed statistics can be collected. Because SSL and HTTP statistics can overlap, it is recommended to only trust HTTP statistics.
<ClientLocal>The traffic between the Loopback client and STON can be included in statistics.
OFF (default)Will not be included.ONWill be included.
<OriginLocal>The traffic between STON and the Loopback origin server will be included.
OFF (default)Will not be included.ONWill be included.
Host Aggregate Statistics¶
Host statistics are the aggregate statistics of all the virtual hosts that run on the lowest level. The statistics can be provided in JSON and XML formats.

If a caching object is created and the corresponding object is initialized, it is considered a hit. On the other hand, if the caching object is missing or the object is not initialized from the origin server, it does not count as a hit. The response code is unrelated to the hit ratio.
HTTP and File I/O share the virtual host.
The RequestHitRatio of File I/O accessed via Apache will become 0%. The HTTP server, however, accesses cached files due to File I/O, making the RequestHitRatio 100%. ByteHitRatio is calculated as the ratio of the origin inbound to either HTTP outbound or File I/O outbound.
ByteHitRatio (unit: 0.01%, average)The transfer ratio of the origin server to the client.(Client Outbound - Origin Server Inbound) / Client Outbound
If the origin server is much faster or the client session closes quickly, then the total ratio can become a negative value.
FileSystemIndependent FileSystem statistics that do not count other stat values.RequestHitRatio (unit: 0.01%, average)Hit ratio based on File I/O.ByteHitRatio (unit: 0.01%, average)Transfer ratio of origin server to File I/O.Outbound (unit: bytes, average)Size of data that goes through File I/O.Session (average)The number of threads in the File I/O process.
Note
These statistics are only provided in five-minute increments.
HttpCountSumThe total number of HTTP transactions.HttpRequestHitSumThe cache hit results.

View¶
View is a method that ties multiple virtual hosts into one to extract statistics. The concept came from viewing multiple tables as one table in a database. As shown below, the setup is very simple.
# vhosts.xml
<Vhosts>
<Vhost> ... </Vhost>
<Vhost> ... </Vhost>
... (omitted) ...
<View Name="SK">
<Vhost>...</Vhost>
<Vhost>...</Vhost>
</View>
<View Name="KT">
<Vhost>...</Vhost>
<Vhost>...</Vhost>
<Vhost>...</Vhost>
</View>
<View Name="LG">
<Vhost>...</Vhost>
<Vhost>...</Vhost>
</View>
</Vhosts>
View can even be set up with virtual hosts that don’t exist. The following are the formats that View provides statistics in.
- Realtime XML/JSON
- SNMP - cache(1.3.6.1.4.1.40001.1.4).10 ~ 12
Let’s explore an example where View can be used. Say there are three administrators running communities for their favorite sports: baseball.com, basketball.com, and football.com.
# vhosts.xml
<Vhosts>
<Vhost Name="baseball.com"> ... </Vhost>
<Vhost Name="basketball.com"> ... </Vhost>
<Vhost Name="football.com"> ... </Vhost>
</Vhosts>
They decide to come together to open a combined sports community service, choosing sports.com as the domain name to encompass all the different sports. The objectives that must be met by the development/management team are as follows.
- The combined service must be provided through sports.com.
- The existing domains and services must be maintained for the existing users.
- The development teams must be combined. The management teams must be combined.
- Only the home page should be developed, connecting to existing services via links.
To realistically meet these demands, the development team decides to specify the existing domains as part of the first directory, as shown below.
# Existing services
http://baseball.com/standing/list.html
http://basketball.com/stats/2014/view.html
http://football.com/player/messi.php
# Combined service
http://sports.com/baseball/standing/list.html
http://sports.com/basketball/stats/2014/view.html
http://sports.com/football/player/messi.php
This can easily be configured using the URL preprocessor.
# vhosts.xml
<Vhosts>
<Vhost Name="baseball.com"> ... </Vhost>
<Vhost Name="basketball.com"> ... </Vhost>
<Vhost Name="football.com"> ... </Vhost>
<URLRewrite>
<Pattern>sports.com/(.*)/(.*)</Pattern>
<Replace>#1.com/#2</Replace>
</URLRewrite>
</Vhosts>
The newly merged management team must now monitor not only their individual services but also the combined service (e.g. traffic, session, response codes). Most administrators familiar with SNMP will set up View to obtain these combined statistics.
# vhosts.xml
<Vhosts>
<Vhost Name="baseball.com"> ... </Vhost>
<Vhost Name="basketball.com"> ... </Vhost>
<Vhost Name="football.com"> ... </Vhost>
<URLRewrite>
<Pattern>sports.com/(.*)/(.*)</Pattern>
<Replace>#1.com/#2</Replace>
</URLRewrite>
<View Name="sports.com">
<Vhost>baseball.com</Vhost>
<Vhost>basketball.com</Vhost>
<Vhost>football.com</Vhost>
</View>
</Vhosts>
As seen in the above example, the combination of URL Rewrite and View can effectively tie existing sites together into a single service.
View Statistics¶
Provides statistics identical to the virtual host statistics, with the only difference being the names of the tags, as shown below.
"View": <View ...>
[ ...
{ ... }, </View>
{ ... }, <View> ... </View>
] <View> ... </View>
Checking the Virtual Host List¶
The virtual host list can be checked.
http://127.0.0.1:10040/monitoring/vhostslist
The results are returned in JSON format.
{
"version": "2.0.0",
"method": "vhostslist",
"status": "OK",
"result": [ "www.example.com","www.winesoft.com", "site1.com" ]
}
Caching Information¶
The status of files being cached can be monitored. Generally, files can be distinguished by URLs, but if the same URL can have different options (e.g. Accept-Encoding), then there may also be multiple files.
http://127.0.0.1:10040/monitoring/fileinfo?url=example.com/sample.dat
The results are returned in JSON format. The following is the result of looking up the information of a /sample.dat file.
{

"method": "fileinfo",
"status": "OK",
"result":
