Re: ignite cache metrics...
Hello Kay, Yes, get for a key means hit or miss basically. So you should enable cache metrics: https://apacheignite.readme.io/docs/cache-metrics And use something like hits/(hits+misses). Would that reflect the metric that you want to look at? Best regards, Anton -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
ignite cache metrics...
Hello, I'm curious about cache hit ratio. How do we calculate the Hit rate of Cache? Getting data means getting hit rates? Thank you -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Ignite Cache metrics on K8s
Hi, I am trying to fetch some cache metrics from Ignite 2.5 running on k8s. Enabled the cache level metrics by setting the below property in ignite config xml for specific cache. But both "ignite_org_apache_ignite_internal_processors_cache_cacheclustermetricsmxbeanimpl_cacheputs" and "ignite_org_apache_ignite_internal_processors_cache_cachelocalmetricsmxbeanimpl_averageputtime" value is coming as 0 while am able to get values for "ignite_org_apache_ignite_internal_processors_cache_cacheclustermetricsmxbeanimpl_keysize" Are there any other property that I need to set to get these metrics? I am injecting data using IgniteDataStreamer. Regards, Mahesh
Unable to get the ignite cache metrics
Hi I brought ignite server on k8s cluster. Set the below property for a cache i wanted to check the metrics Then i started the client and tried to push the data into ignite cache. I am able to see the data in the cache. But the values for the following metrics i am getting as 0. Can some one let me know why is this. ignite_org_apache_ignite_internal_processors_cache_cachelocalmetricsmxbeanimpl_cacheputs = 0 ignite_org_apache_ignite_internal_processors_cache_cachelocalmetricsmxbeanimpl_averageputtime = 0 -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Ignite Cache Metrics
Hi, Thanks for your reply. It's quite possible that rebalancing might be taking place which led to this difference. As after some time I got matching numbers. But I am still not clear why is metrics().getOffHeapAllocatedSize() = 0 . -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Ignite-Cache-Metrics-tp13624p13809.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
Re: Ignite Cache Metrics
Hi, Are you sure that your cache was not accessed in the same time by another nodes/threads? Are you sure that rebalance was finished? Could you share some simple reproducer with us? I've tried to reproduce same behavior, but OFFHEAP, PRIMARY & BACKUP was equal to each other. Also, right after streaming of data metrics().getOffHeapPrimaryEntriesCount() was a little bit smaller than these sizes, but in a short time it became equal to them too. Here are other memory metrics: https://apacheignite.readme.io/docs/memory-and-cache-metrics Evgenii -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Ignite-Cache-Metrics-tp13624p13806.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
Ignite Cache Metrics
Hi, I am trying to access Ignite-2.0.0 cache metrics. I have loaded one cache into my cluster of 2 nodes with 1 backup (onHeapEnabled=false) At an instant of time I am getting below ignite cache size using : itemCache.size(CachePeekMode.OFFHEAP) = 2645679 itemCache.size(CachePeekMode.PRIMARY) = 2645679 itemCache.size(CachePeekMode.BACKUP) = 2635802 itemCache.metrics().getOffHeapPrimaryEntriesCount() = 2638451 Why is there a difference in above numbers. In my understanding primary and backup count should be same and same as that of all the entries in cache . Also count fetched using cache.size and cache.metrics should give same numbers. Also can someone tell me how can I get off heap memory used . When I do itemCache.metrics().getOffHeapAllocatedSize() , I get '0' always. Is there some other metric available to fetch off heap memory metrics. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Ignite-Cache-Metrics-tp13624.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
