Andrzej Bialecki resolved SOLR-11036. -------------------------------------- Resolution: Fixed > MetricsHandler should report disk stats for solr.data.home > ---------------------------------------------------------- > > Key: SOLR-11036 > URL: https://issues.apache.org/jira/browse/SOLR-11036 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level. Issues are Public) > Components: metrics, SolrCloud > Affects Versions: 7.0 > Reporter: Shalin Shekhar Mangar > Assignee: Andrzej Bialecki > Labels: metrics > Fix For: 7.0, master (8.0), 7.1 > > Attachments: SOLR-11036.patch > > > The totalSpace and usableSpace reported by Metrics API are still based on > coreRootDirectory (which is used as the instance dir for individual cores). > SOLR-6671 introduced a new solr.data.home configuration for the root > directory of all data dirs. So we should expose data home's disk metrics as > well. > Since the current metric names are just totalSpace and usableSpace under the > Container group, we need to figure out how to differentiate between them and > the data home's metrics. A few options: > # We can introduce new metrics such as dataHomeTotalSpace and > dataHomeUsableSpace. > # We use the current names for the data home's metrics and introduce new ones > for coreRootDirectory > I lean towards #2 because of backcompat reasons. Existing users (and > monitoring vendors/products) would be using the existing metric names to > track disk stats for their solr installations. If a user configures a > solr.data.home then they shouldn't get a surprise one day if the data home > directory runs out of space when they have monitoring already in place which > used to work for earlier versions of Solr. The probability of surprise still > exists because one fine day you can run out of space for the > coreRootDirectory and solr will refuse to create any cores but that is a less > likely scenario than running out of disk space because of increasing size of > data directories. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
