I installed PMM 1.0.4 yesterday. From the beginning when there were only one or two test hosts, the graphs were still working. But later they were not working when I added several hosts into pmm-server one by one.
pmm-admin list
RUNNING is all YES
pmm-admin check-network --no-emoji
- Client --> Server all is OK
- Client <-- Server all is PROBLEM ( I already checked the firewall which was stopped.)
The following is one of my graphs.
Please give me any advice, thanks so much. BTW, PMM is so cool:P
