设置自动刷新间隔 - LogSetFlushInterval ​

函数简介 ​

设置日志自动刷新到文件的时间间隔。

接口名称 ​

LogSetFlushInterval

DLL调用 ​

c
int32_t LogSetFlushInterval(int64_t instance, int64_t loggerHandle, int32_t flushIntervalSeconds);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
loggerHandle长整数型日志实例句柄（0 表示默认实例）。
flushIntervalSeconds整数型自动刷新间隔（秒）。

示例 ​

设为 3 秒；注意 WARN 及以上通常会立即刷新，不必等间隔。

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
const int64_t logger = 0; // 默认实例

ola.LogSetAsync(logger, 1);
int ret = ola.LogSetFlushInterval(logger, 3); // 3 seconds
if (ret != 1) {
    return;
}
ola.LogInfo("flush every 3s");
// WARN/ERROR/CRITICAL 通常立即 flush；INFO 可等间隔或 LogFlush
csharp
using System;
using OLAPlug;

var ola = new OLAPlugServer();
long logger = 0;

ola.LogSetAsync(logger, 1);
int ret = ola.LogSetFlushInterval(logger, 3); // 3 seconds
if (ret != 1) return;
ola.LogInfo("flush every 3s");
// WARN/ERROR/CRITICAL 通常立即 flush；INFO 可等间隔或 LogFlush
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
logger = 0

ola.LogSetAsync(logger, 1)
ret = ola.LogSetFlushInterval(logger, 3)  # 3 seconds
if ret != 1:
    raise RuntimeError("failed")

// WARN/ERROR/CRITICAL 通常立即 flush；INFO 可等间隔或 LogFlush

返回值 ​

返回值说明
1成功。
0失败。

注意事项 ​

项目说明
默认值0（每条日志立即刷新到文件）。
设置为 0 时设置为 0 时，每条日志都立即写入文件（最安全，但性能较低）。
设置为 > 0 时设置为 > 0 时，只有 WARN 及以上级别的日志才会立即刷新，其他日志会缓冲定期刷新。
无论设置如何无论设置如何，都可以手动调用 LogFlush 强制刷新。
此设置立即生效此设置立即生效，无需重新初始化。
