pt-heartbeat --check should not write to the heartbeat table

[monty solomon]

% pt-heartbeat --host localhost -D heartbeat --check

DBD::mysql::db do failed: The MySQL server is running with the --read-only option so it cannot execute this statement [for Statement "INSERT INTO `heartbeat`.`heartbeat` (server_id, ts) VALUES ('639407132', UTC_TIMESTAMP())"] at /usr/bin/pt-heartbeat line 5953.

pt-heartbeat still tries to write to the table when --check-read-only is added

% pt-heartbeat --host localhost -D heartbeat --check --check-read-only

DBD::mysql::db do failed: The MySQL server is running with the --read-only option so it cannot execute this statement [for Statement "INSERT INTO `heartbeat`.`heartbeat` (server_id, ts) VALUES ('639407132', UTC_TIMESTAMP())"] at /usr/bin/pt-heartbeat line 5953.

The same is true for --monitor

% pt-heartbeat --host localhost -D heartbeat --monitor

DBD::mysql::db do failed: The MySQL server is running with the --read-only option so it cannot execute this statement [for Statement "INSERT INTO `heartbeat`.`heartbeat` (server_id, ts) VALUES ('639407132', UTC_TIMESTAMP())"] at /usr/bin/pt-heartbeat line 5953.

% pt-heartbeat --host localhost -D heartbeat --monitor --check-read-only

DBD::mysql::db do failed: The MySQL server is running with the --read-only option so it cannot execute this statement [for Statement "INSERT INTO `heartbeat`.`heartbeat` (server_id, ts) VALUES ('639407132', UTC_TIMESTAMP())"] at /usr/bin/pt-heartbeat line 5953.
