[metrics-web/master] Rewrite the consensus-health checker.

commit 2f6c2bdc3d2b5393f8c884cf333a5e54ab4d45dc Author: Karsten Loesing <karsten.loesing(a)gmx.net> Date: Wed Oct 12 15:22:18 2011 +0200 Rewrite the consensus-health checker. The major change in this rewrite is that the consensus-health checker is now independent from importing descriptors into the metrics database. It now downloads its own consensus and votes, triggered by its own cronjob. This rewrite is the second in a series of refactorings to decouple the many metrics-web components. The first refactoring was to move ExoneraTor data into its own database and use a separate database importer for it. The goal will be to have separate component for each functionality without dependencies, so that every component can fail independent from the rest. Another effect of the rewrite is that the consensus-health checker can now be extended more easily by adding new reports or new checks. --- build.xml | 9 + config.template | 8 - src/org/torproject/chc/Archiver.java | 120 +++ src/org/torproject/chc/Downloader.java | 190 ++++ src/org/torproject/chc/Main.java | 70 ++ src/org/torproject/chc/MetricsWebsiteReport.java | 841 +++++++++++++++++ src/org/torproject/chc/NagiosReport.java | 238 +++++ src/org/torproject/chc/Parser.java | 162 ++++ src/org/torproject/chc/Report.java | 23 + src/org/torproject/chc/Status.java | 185 ++++ src/org/torproject/chc/StatusEntry.java | 48 + src/org/torproject/chc/StdOutReport.java | 288 ++++++ src/org/torproject/ernie/cron/Configuration.java | 14 - .../ernie/cron/ConsensusHealthChecker.java | 993 -------------------- src/org/torproject/ernie/cron/Main.java | 17 +- .../ernie/cron/RelayDescriptorParser.java | 13 +- 16 files changed, 2178 insertions(+), 1041 deletions(-) diff --git a/build.xml b/build.xml index 9194ccd..32a450f 100644 --- a/build.xml +++ b/build.xml @@ -60,6 +60,15 @@ </java> </target> +  + <target name="chc" depends="compile"> + <java fork="true" + maxmemory="512m" + classname="org.torproject.chc.Main"> + <classpath refid="classpath"/> + </java> + </target> +  <target name="run" depends="compile"> <java fork="true" diff --git a/config.template b/config.template index e0fa743..8c56909 100644 --- a/config.template +++ b/config.template @@ -36,14 +36,6 @@ ## files will be overwritten! #RelayDescriptorRawFilesDirectory pg-import/ # -## Write statistics about the current consensus and votes to the -## website -#WriteConsensusHealth 0 -# -## Write Nagios status file containing potential problems with the latest -## consensus -#WriteNagiosStatusFile 0 -# ## Write bridge stats to disk #WriteBridgeStats 0 # diff --git a/src/org/torproject/chc/Archiver.java b/src/org/torproject/chc/Archiver.java new file mode 100644 index 0000000..6271348 --- /dev/null +++ b/src/org/torproject/chc/Archiver.java @@ -0,0 +1,120 @@ +/* Copyright 2011 The Tor Project + * See LICENSE for licensing information */ +package org.torproject.chc; + +import java.io.*; +import java.util.*; + +/* Load the last network status consensus and corresponding votes from + * disk and save newly downloaded ones to disk. */ +public class Archiver { + + /* Local directory containing cached consensuses and votes. */ + private File cachedFilesDirectory = new File("chc-cache"); + + /* Copy of the most recent cached consensus and votes. */ + private String loadedConsensus; + private List<String> loadedVotes = new ArrayList<String>(); + + /* Load the most recent cached consensus and votes to memory. */ + public void loadLastFromDisk() { + if (!this.cachedFilesDirectory.exists()) { + return; + } + String lastValidAfter = this.findLastConsensusPrefix(); + if (lastValidAfter != null) { + for (File file : this.cachedFilesDirectory.listFiles()) { + if (file.isDirectory() || + !file.getName().startsWith(lastValidAfter)) { + continue; + } + String content = null; + try { + FileInputStream fis = new FileInputStream(file); + BufferedInputStream bis = new BufferedInputStream(fis); + ByteArrayOutputStream baos = new ByteArrayOutputStream(); + int len; + byte[] data = new byte[1024]; + while ((len = bis.read(data, 0, 1024)) >= 0) { + baos.write(data, 0, len); + } + bis.close(); + byte[] allData = baos.toByteArray(); + content = new String(allData); + } catch (IOException e) { + System.err.println("Could not read cached status from file '" + + file.getAbsolutePath() + "'.
