Claims (10)

1. An automatic log space recycling method is characterized by comprising the following steps:
acquiring the utilization rate of log partition space of each host;
judging whether the utilization rate of the log partition space of each host reaches an alarm threshold value;

and clearing the log files under the log partition file directory of the host computer which generates the current alarm and reserving the log partition file directory.
2. The method of automatic log space reclamation according to claim 1, wherein the flushing the log files under the log partition file directory of the host generating the alert and reserving the log partition file directory comprises:
emptying the log file of log rotation dump according to the size of the log file;
after the log file of the log rotation dump is emptied, judging whether the host log partition space alarm is eliminated;
and if the host log partition space alarm is not eliminated, clearing other log files according to the size of the log files until the host log partition space alarm is eliminated.
3. The method of automatic log space reclamation according to claim 1, wherein the flushing the log files under the log partition file directory of the host generating the alert and reserving the log partition file directory comprises:
clearing the log file with the log file generation time longer than a first preset time;
judging whether the host log partition space alarm is eliminated;
and if the host log partition space alarm is not eliminated, clearing other log files with the log file generation time not longer than the first preset time according to the size of the log file until the host log partition space alarm is eliminated.
4. The method according to claim 1, wherein after the determining that the host generates the log partition space alarm, the step of emptying the log file under the log partition file directory of the host generating the alarm and retaining the log partition file directory further comprises:
judging whether the alarm duration of the host generating the alarm reaches a second preset time or not;
if yes, entering a step of clearing the log files under the log partition file directory of the host computer generating the alarm and reserving the log partition file directory.
5. The automatic log space recovery method according to any one of claims 1 to 4, wherein the alarm threshold value includes: a first alarm threshold and a second alarm threshold;
if the usage rate of the log partition space of the other hosts reaches the second alarm threshold value but does not reach the first alarm threshold value when the log files under the log partition file directory of the host which generates the alarm at present are emptied, continuing to execute the step of emptying the log files under the log partition file directory of the host which generates the alarm at present;
and if the utilization rate of the log partition spaces of the other hosts reaches the first alarm threshold, executing the clearing of the log files under the log partition file directory of the other hosts.
6. The method according to claim 5, wherein the steps of flushing the log file under the log partition file directory of the host computer that is currently generating the alarm and reserving the log partition file directory further comprise:
