Hello @Xun Zhai

Just for your information: GridGain has a GUI tool called Visor that can
show IGFS metrics
 and also has two panels file manager that could navigate IGFS/HDFS/Local
file systems,
 copy files between them, view files and much more.

But you will need to use GridGain build.

Take a look: https://gridgain.readme.io/docs/visor-gui#igfs-tab

Hi,

Currently you can only access IGFS programatically, using
*IgniteFileSystem.metrics()
*method. If this is not an option for you, please attach the following:
1) Ignite configuration
2) Content of *core-site.xml* used for job execution.
3) Command line you use to start the job.

Vladimir.

Hi @Vasiliy
The reason why i want to watch IGFS cache informations is because of with
SecondryFileSystem it looks like my job's performance has no obviously
change, i think this is because of no cache is hited, am i right? or could
you give me some advices to analysis this situation.

Best Regards

Hello @Xun Zhai

To enable the hits, misses, reads, writes metrics please enable
statisticsEnabled property in cache configuration.
The data and metadata caches for IGFS contains specific information, that
not have direct reflection with stored data. That data have no meaning for
user.
