Methods
deleteLog(request[, options][, callback]) → Promise
Deletes all the log entries in a log. The log reappears if it receives new entries. Log entries written shortly before the delete operation might not be deleted.
Example
const logging = require('@google-cloud/logging');
const client = new logging.v2.LoggingServiceV2Client({
// optional auth parameters.
});
const formattedLogName = client.logPath('[PROJECT]', '[LOG]');
client.deleteLog({logName: formattedLogName}).catch(err => {
console.error(err);
});

request |
Object |
|
The request object that will be sent. Values in
|
||||||||
|
options |
Object |
Yes |
Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details. |
||||||||
|
callback |
function(nullable Error) |
Yes |
The function which will be called with the result of the API call. |
- Returns
-
Promise- The promise which resolves when API call finishes. The promise has a method named "cancel" which cancels the ongoing API call.
getProjectId(callback)
Return the project ID used by this class.
Parameter
| Name | Type | Optional | Description |
|---|---|---|---|
|
callback |
function(Error, string) |
|
the callback to be called with the current project Id. |
listLogEntries(request[, options][, callback]) → Promise
Lists log entries. Use this method to retrieve log entries from Logging. For ways to export log entries, see Exporting Logs.
Example
const logging = require('@google-cloud/logging');
const client = new logging.v2.LoggingServiceV2Client({
// optional auth parameters.
});
// Iterate over all elements.
const formattedResourceNames = [];
client.listLogEntries({resourceNames: formattedResourceNames})
.then(responses => {
const resources = responses[0];
for (const resource of resources) {
// doThingsWith(resource)
}
})
.catch(err => {
console.error(err);
});
// Or obtain the paged response.
const formattedResourceNames = [];
const options = {autoPaginate: false};
const callback = responses => {
// The actual resources in a response.
const resources = responses[0];
// The next request if the response shows that there are more responses.
const nextRequest = responses[1];
// The actual response object, if necessary.
// const rawResponse = responses[2];
for (const resource of resources) {
// doThingsWith(resource);
}
if (nextRequest) {
// Fetch the next page.
return client.listLogEntries(nextRequest, options).then(callback);
}
}
client.listLogEntries({resourceNames: formattedResourceNames}, options)

Parameters
| Name | Type | Optional | Description | ||||||||||||||||||||||||

|
request |
Object |

|
||||||||||||||||||||||||
|
options |
Object |
Yes |
Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details. |
||||||||||||||||||||||||
|
callback |
function(nullable Error, nullable Array, nullable Object, nullable Object) |
Yes |
The function which will be called with the result of the API call. The second parameter to the callback is Array of LogEntry. When autoPaginate: false is specified through options, it contains the result in a single response. If the response indicates the next page exists, the third parameter is set to be used for the next request object. The fourth parameter keeps the raw response object of an object representing ListLogEntriesResponse. |
- Returns
-
Promise-
The promise which resolves to an array. The first element of the array is Array of LogEntry.
When autoPaginate: false is specified through options, the array has three elements. The first element is Array of LogEntry in a single response. The second element is the next request object if the response indicates the next page exists, or null. The third element is an object representing ListLogEntriesResponse.
The promise has a method named "cancel" which cancels the ongoing API call.
-
listLogEntriesStream(request[, options]) → Stream
Equivalent to listLogEntries, but returns a NodeJS Stream object.
This fetches the paged responses for listLogEntries continuously and invokes the callback registered for 'data' event for each element in the responses.
The returned object has 'end' method when no more elements are required.
autoPaginate option will be ignored.
Example
const logging = require('@google-cloud/logging');
const client = new logging.v2.LoggingServiceV2Client({
// optional auth parameters.
});
const formattedResourceNames = [];
client.listLogEntriesStream({resourceNames: formattedResourceNames})
.on('data', element => {
// doThingsWith(element)
}).on('error', err => {
console.log(err);
});
