Package net.i2p.router.web

Class StatSummarizer

java.lang.Object

net.i2p.router.web.StatSummarizer

All Implemented Interfaces:

Runnable, ClientApp

public class StatSummarizer
extends Object
implements Runnable, ClientApp

A thread started by RouterConsoleRunner that checks the configuration for stats to be tracked via jrobin, and adds or deletes RRDs as necessary. This also contains methods to generate xml or png image output. The rendering for graphs is in SummaryRenderer. To control memory, the number of simultaneous renderings is limited.

Since:

0.6.1.13

renderPng

public boolean renderPng(Rate rate,
 OutputStream out)
                  throws IOException

Throws:

IOException

renderPng

public boolean renderPng(Rate rate,
 OutputStream out,
 int width,
 int height,
 boolean hideLegend,
 boolean hideGrid,
 boolean hideTitle,
 boolean showEvents,
 int periodCount,
 int end,
 boolean showCredit)
                  throws IOException

This does the single data graphs. For the two-data bandwidth graph see renderRatePng(). Synchronized to conserve memory.

Parameters:

end - number of periods before now

Returns:

success

Throws:

IOException

renderPng

@Deprecated
public boolean renderPng(OutputStream out,
 String templateFilename)
                  throws IOException

Deprecated.

unused

Throws:

IOException

getXML

public boolean getXML(Rate rate,
 OutputStream out)
               throws IOException

Throws:

IOException

renderRatePng

public boolean renderRatePng(OutputStream out,
 int width,
 int height,
 boolean hideLegend,
 boolean hideGrid,
 boolean hideTitle,
 boolean showEvents,
 int periodCount,
 int end,
 boolean showCredit)
                      throws IOException

This does the two-data bandwidth graph only. For all other graphs see renderPng() above. Synchronized to conserve memory.

Parameters:

end - number of periods before now

Returns:

success

Throws:

IOException

parseSpecs

public Set<Rate> parseSpecs(String specs)

Parameters:

specs - statName.period,statName.period,statName.period
