I'm using b300 switches. I meet latency issues in my fabric. Brocade provides SAN Health, availables only with MS Windows. Does San Health will help me to find where latency issues occures ?

I would use the CLI interface on each of your switches to probe them , and see what's going on.
"porterrshow" is a pretty handy command to run to give you a look at whats going on.

Thank you for your answer.
I have errors in the fields er_enc_out and er_bad_os. What i understood is that this kind of error if often liked with hardware issues. I changed all my SFP. But it is yet the same situation. I don't have enougth fibers to change all my fibers.
But I am doubtful. All my used ports have errors. I can't think that all my ports are damaged.
Your opinion ?

Post switchshow and porterrshow of 2 switches in the same fabric - one thats affected and pick another one thats connected to it.
Execute portstatsclear on both switches before the first collection.
Collect o/p in a text file with a 2hr gap during peak hours.
Looks like the source of the error is not on the switch you are probing, If I remember right, enc_out's can propagate through the fabric.
The only way to isolate the problem is to observe delta of each port error and try to figure out the problem. Also look at fabriclog -s on all switches and check if there are flapping ports, if yes stop the cause, can help in isolation of problems.
