Utilizzare ListRules con un AWS SDK o CLI

Elenca tutte le regole per un router di eventi.

    /// <summary>
    /// List the rules on an event bus.
    /// </summary>
    /// <param name="eventBusArn">The optional ARN of the event bus. If empty, uses the default event bus.</param>
    /// <returns>The list of rules.</returns>
    public async Task<List<Rule>> ListAllRulesForEventBus(string? eventBusArn = null)
    {
        var results = new List<Rule>();
        var request = new ListRulesRequest()
        {
            EventBusName = eventBusArn
        };
        // Get all of the pages of rules.
        ListRulesResponse response;
        do
        {
            response = await _amazonEventBridge.ListRulesAsync(request);
            results.AddRange(response.Rules);
            request.NextToken = response.NextToken;

        } while (response.NextToken is not null);

        return results;
    }

Per visualizzare un elenco di tutte le regole CloudWatch degli eventi

Questo esempio visualizza tutte le regole CloudWatch Events della regione:

aws events list-rules

Per visualizzare un elenco di regole CloudWatch Events che iniziano con una determinata stringa.

Questo esempio visualizza tutte le regole CloudWatch Events nella regione il cui nome inizia con «Daily»:

aws events list-rules --name-prefix "Daily"

Abilita una regola utilizzando il nome della stessa.

    public static void listRules(EventBridgeClient eventBrClient) {
        try {
            ListRulesRequest rulesRequest = ListRulesRequest.builder()

                    .limit(10)
                    .build();

            ListRulesResponse response = eventBrClient.listRules(rulesRequest);
            List<Rule> rules = response.rules();
            for (Rule rule : rules) {
