Example 1 with EnvironmentStats

use of com.sleepycat.je.EnvironmentStats in project voldemort by voldemort.

the class BdbSplitStorageEngineTest method getMaxCacheUsage.

private long getMaxCacheUsage(EnvironmentConfig environmentConfig, DatabaseConfig databaseConfig) throws DatabaseException {
    File dirA = new File(bdbMasterDir + "/" + "storeA");
    if (!dirA.exists()) {
        dirA.mkdirs();
    }
    Environment environmentA = new Environment(dirA, environmentConfig);
    Database databaseA = environmentA.openDatabase(null, "storeA", databaseConfig);
    BdbStorageEngine storeA = BdbStorageEngineTest.makeBdbStorageEngine("storeA", environmentA, databaseA, new BdbRuntimeConfig(), this.prefixPartitionId);
    File dirB = new File(bdbMasterDir + "/" + "storeB");
    if (!dirB.exists()) {
        dirB.mkdirs();
    }
    Environment environmentB = new Environment(dirB, environmentConfig);
    Database databaseB = environmentB.openDatabase(null, "storeB", databaseConfig);
    BdbStorageEngine storeB = BdbStorageEngineTest.makeBdbStorageEngine("storeB", environmentB, databaseB, new BdbRuntimeConfig(), this.prefixPartitionId);
    long maxCacheUsage = 0;
    for (int i = 0; i <= 10000; i++) {
        byte[] value = new byte[(int) (CACHE_SIZE / 10000)];
        // try to push values in cache
        storeA.put(TestUtils.toByteArray(i + "A"), new Versioned<byte[]>(value), null);
        storeA.get(TestUtils.toByteArray(i + "A"), null);
        storeB.put(TestUtils.toByteArray(i + "B"), new Versioned<byte[]>(value), null);
        storeB.get(TestUtils.toByteArray(i + "B"), null);
        EnvironmentStats statsA = environmentA.getStats(new StatsConfig());
        EnvironmentStats statsB = environmentB.getStats(new StatsConfig());
        long totalCacheSize = statsA.getCacheTotalBytes() + statsB.getCacheTotalBytes();
        System.out.println("A.size:" + statsA.getCacheTotalBytes() + " B.size:" + statsB.getCacheTotalBytes() + " total:" + totalCacheSize + " max:" + maxCacheUsage + " cacheMax:" + environmentA.getConfig().getCacheSize());
        System.out.println("Shared.A:" + statsA.getSharedCacheTotalBytes() + " nSharedEnv:" + statsA.getNSharedCacheEnvironments());
        maxCacheUsage = Math.max(maxCacheUsage, totalCacheSize);

}

Example 2 with EnvironmentStats

use of com.sleepycat.je.EnvironmentStats in project qpid-broker-j by apache.

the class EnvironmentUtils method getEnvironmentStatistics.

public static Map<String, Map<String, Object>> getEnvironmentStatistics(Environment environment, boolean reset) {
    StatsConfig config = new StatsConfig();
    config.setClear(reset);
    config.setFast(false);
    EnvironmentStats stats = environment.getStats(config);
    Collection<StatGroup> statGroups = stats.getStatGroups();
    return getStatsFromStatGroup(statGroups);
}
