What does Threads_connected=-1 signify in MySQL? I was running the following: mysqladmin -u root -p ext -ri 10 | grep Threads_connected and was kind of surprised to find that Threads_connected could be -1:

| Threads_connected                 | 1            |
| Threads_connected                 | -1           |
| Threads_connected                 | 1            |
| Threads_connected                 | -1           |


What does the -1 signify?

This is on MySQL 5.0.77 on x86_64.

Thanks!
